Depending on their skill and adaptability

Honestly, the loss of Symbiosis doesn't affect as many druids as you think it does. Depending on their skill and adaptability as a player they may have stopped using it during the first few weeks of new content (like myself) and those that still do use it do so for the CD that it gives their -target- as opposed to the one that it gives themselves (ie: Shadow priest tranq when things get tight even though it's weak and almost like www.euwowgold.com they're not doing anything at all. but the numbers helped once or twice I suppose...)

The loss of this ability to make other classes have more utility is only slightly saddening. But with the changes to the game, most of us that play the class and play it well won't notice a difference with the changes to Barkskin and Survival instincts.

All in all, I agree with the loss of Symb because it was damn near useless to begin with.
