The enhancement tree is designed to help out shamans who want to get closer to the action. Those shamans who want to be in doing melee damage. The enhancement tree also augments shock spells with the thought that enhancement shamans should be using them for utility and for added damage.
Ancestral Knowledge
Description: Increases your maximum mana
Ranks:Rank 1 by 1%
Rank 2 by 2%
Rank 3 by 3%
Rank 4 by 4%
Rank 5 by 5%
Commentary: This talent doesn't produce much for extra mana. 5% is simply not much to look at. The big plus of this is that it is a small gain and it is commonly taken over Shield specialization because most shaman do not use shield specialization and even a little more mana is better than totally wasting the 5 talent points.

Shield Specialization
Description: Increases your chance to block attacks with a shield by X% and increases the amount blocked by X%
Ranks:Rank 1 chance to block by 1%, amount blocked by 5%
Rank 2 chance to block by 2%,
amount blocked by 10%
Rank 3 chance to block by 3%, amount blocked by 15%
Rank 4 chance to block by 4%, amount blocked by 20%
Rank 5 chance to block by 5%, amount blocked by 25%
Commentary: This talent is seldom worth taking. If you are using a shield and tanking for some reason then it might be worth taking. The ability to block with a shield does not happen if you are casting. Enhancement shamans will primarily be casting and kiting. Restoration shamans will be casting lots of heals. Enhancement shamans will normally have either a two-handed weapon or be dual-wielding. That makes increase chance to block and increased damage absorbed useless.
Guardian Totems
Description: Increases the amount of damage reduced by your Stoneskin Totem and Windwall Totem by XX% and reduces the cooldown of your Grounding Totem.
Ranks:Rank 1 damage reduced by 10 %, cooldown reduced by 1 second
Rank 2 damage reduced by 20@, cooldown reduced by 2 seconds
Commentary: The Guardian Totems talent is most useful in PvP battles, because of the reduction in Grounding Totem. The increase to Stoneskin and Windwall totem is useful when you are using said totems a lot. This talent is more dependent on the style of play.
Thundering Strikes
Description: Improves your chance to get a critical strike with your weapon attacks
Ranks: Rank 1 by 1%
Rank 2 by 2%
Rank 3 by 3%
Rank 4 by 4%
Rank 5 by 5%

Commentary: If you are playing an enhancement shaman this is a have to have talent. The added chance to get a critical hit is great amount of damage. This talent is also a prerequisite for Flurry another important enhancement shaman talent.
Improved Ghost Wolf
Description: Reduces the cast time of your Ghost Wolf spell
Ranks:Rank 1 by 1 second
Rank 2 by 2 seconds
Commentary: This talent is useful for reducing down time. Two seconds does not seem like much, but the number of times you will use the Ghost Wolf spell throughout your time playing is a lot of time saved. With two ranks of Improved Ghost Wolf, it makes the Ghost Wolf spell only a 1 second cast time. That makes Ghost wolf a spell that is commonly used to get away from an enemy. This is considered an okay filler talent if needed to get deeper in the enhancement tree.
Improved Lightning Shield
Description: Increases the damage done by your Lightning Shield orbs
Ranks: Rank 1 by 5%
Rank 2 by 10%
Rank 3 by 15%
Commentary: Lightning Shield is by far one of the most effective and mana efficient spells as it is. This talent furthers how effective and efficient this spell is. The down side of this is that for it to be useful you need to be getting hit. If you are an elemental or restoration shaman this talent is not worth the points at all. If you are leveling as enhancement you should consider this a have to talent.
Enhancing Totems
Description: Increases the effect of your Strength of Earth and Grace of Air Totems
Ranks: Rank 1 by 8%
Rank 2 by 15%
Commentary: This talent will increase max rank Strength of Earth Totem by 13 and max rank Grace of Air Totem by 12. This talent is for a more group based player. The bonus is not worth it for a solo player. At higher levels you will be using other totems that won't allow you to use Strength of Earth, or Grace of Air totem. This is good for group leveling and maybe for a filler talent if needed to get to higher tiers of the enhancement tree.

Shamanistic Focus
Description: After landing a melee critical strike, you enter a Focused state. The Focused state reduces the mana cost of your next Shock spell by 60%.
Ranks: Rank 1 give the full effect.
Commentary: This talent is very useful to enhancement shamans who are focusing on their chance to get a critical hit with melee weapons. This makes it so the shaman can add to their damage without the mana commitment. This will help your DPS in all situations.
Anticipation
Description: Increases your chance to dodge
Ranks:Rank 1 by 1%
Rank 2 by 2 %
Rank 3 by 3%
Rank 4 by 4%
Rank 5 by 5%
Commentary: The increase to dodge that Anticipation provides is not significant enough to use the five talent points required. There are better places in the enhancement tree to use 5 talent points. If you have spare points and are doing a heavy amount of tanking this will help augment the damage you take.
Flurry
Description: Increases your attack speed by XX% for your next 3 swings after dealing a critical strike.
Ranks: Rank 1 by 10%
Rank 2 by 15%
Rank 3 by 20%
Rank 4 by 25%
Rank 5 by 30%
Commentary: Flurry is a have to have talent for enhancement shamans. The ability to get a haste boost every time you get a critical hit is a huge increase to your damage per encounter. This ability procs off of any critical melee hit or critical spell proc from the weapon.
Toughness
Description: Increases your armor value from items
Ranks:Rank 1 by 2%
Rank 2 by 4%
Rank 3 by 6%
Rank 4 by 8%
Rank 5 by 10%
Commentary: This talent can make a mail wearing shaman even closer to the armor that plate wearers sport. This added defense is useful for shamans that off tank. Otherwise this talent is not worth the five talent points.

Improved Weapon Totems
Description: Increases the melee attack power bonus of your Windfury Totem by XX% and increases the damage caused by your Flametongue Totem by X%.
Ranks: Rank 1 Windfury totem by
15%, Flametongue Totem by 6%
Rank 2 Windfury totem by 30%, Flametongue Totem by 12%
Commentary: This is a talent used by raiding shamans and shamans who are in groups a lot. The reason being that shaman's personal buffs are better than the buffs that come from the totems. The increase to damage is very nice when you are in a group that has a decent amount of melee DPS.
Spirit Weapons
Description: Gives a chance to parry enemy melee attacks and reduces the threat generated by your melee attacks by 30%.
Ranks: Rank 1 give the full effect
Commentary: This talent gives you a chance to parry with your weapon. This is a nice new way for your shaman who is melee the mob to augment their ability to take some hits. This talent is also needed to later on get Dual Wield. The threat reduction is very helpful for shamans who are in a group as DPS. This way you are less likely to pull the mob away from the plate wearing, shield bearing warrior.
Elemental Weapons
Description: Increases the damage caused by your Rockbiter Weapon by X%, your Windfury Weapon effect by XX% and increases the damage caused by your Flametongue Weapon and Frostbrand Weapon by X%.
Ranks: Rank 1 Rockbiter by 7%, Windfury by 13%, and Flametongue/Frostbrand by 5%
Rank 2 Rockbiter by 14%, Windfury by 27%, and Flametongue/Frostbrand by 10%
Rank 3 Rockbiter by 20%, Windfury by 40%, and Flametongue/Frostbrand by 15%
Commentary: This talent makes your self weapon buffs much stronger. If you are going to be doing a lot of tanking or soloing with your shaman this will help your damage output greatly.

2%, an amount equal to 10%

4%, an amount equal to 20%
Rank 3 mana cost reduced by
6%, an amount equal to 30%
Commentary: Mental Quickness is a great talent for those shamans who are hybrids of enhancement and elemental. This works out very well then. This talent is otherwise commonly looked over. With the increase in the use of shocks by enhancement shamans this talent could be come even stronger.
Weapon Mastery
Description: Increases the damage you deal with all weapons
Ranks: Rank 1 by 2%
Rank 2 by 4%
Rank 3 by 6%
Rank 4 by 8%
Rank 5 by 10%

Rank 4 by 8%
Rank 5 by 10%
