Each class gets some new spells and kills in Outland. Some more powerful than others, although many of them are situational in their uses. Check them out:
Druid
Cyclone

This spell sees good use in both PvE and PvP, as it can buy you time to heal yourself without interruption. And it interrupts other people’s spells.
Maim

Another interrupting ability! The stun is helpful, and although the fact that it breaks on damage is a shame, there are definitely scenario’s where it can save your ass.
Lacerate

This skill is most commonly used as a rage dump in between mauls. It is particularly useful for increasing your threat on a single target. Lacerate's threat effect works on undead (which are immune to bleed effects). You wont see the bleed debuff on them, but you do get the threat.
Flight Form

Flying is pretty cheap for Druids, and being able to train this spells at level 68 they get the ability sooner than anyone else. The flight speed is the same as non-epic mounts. It may be slow, but it does allow you to reach Tempest Keep earlier than most, for instance.
Life Bloom

Healing up to 819 over 7 seconds before +healing, this is a really nice and fast HoT. It isn’t always the best option to keep it triple stacked constantly as the short duration can cause problems for your mana regen during a fight, but it definitely is a sweet regen spell.
