I've heard quite a few people state that Druid t6 talents are crap. I'm wondering where this idea is coming from. Clearly from a design standpoint, the entire class is getting pushed into a direction of more hybridization. Instead of forms becoming separate from each other, they are becoming more intertwined, allowing you to pull more abilities from other branches of the class. Instead of the Moonkin being locked in Balance abilities, it will be able to utilize feral and restoration abilities as well. Ferals can utilize more Balance abilities to increase their attack power, yet still be able to perform powerful healing spells to add utility to given situations.
All of this leads to a highly flexible and mobile class that is no longer merely a clone of other existing classes, but an interesting and unique class all its own.
And that's where the level 90 talents come in. The two controversial talents amplify the hybrid nature of the class in a cooldown, or a procc. The final talent is mainly for PvP, allowing the Druid to constantly be on the move without fear of being rooted or snared. Through a 20% instant heal on top of it, and I don't see how anyone could consider that a bad talent.
