We’ve got a number of upcoming changes to the core and spec trees coming in 10.0.5. Our hope is that they fix some underlying issues with the trees while still giving you the same options and overall builds you’ve gotten used to.
One of our goals for the talent tree was to make it impossible or unlikely to pick talents that would do nothing for a character. Druid breaks that guideline in a couple places – Feral can take talents that modify Berserk without taking Berserk, Guardian and Feral can skip Swipe, etc. Most players don’t do these, but we still want to tighten this up.
