We all know in cataclysm the Tree of Life form will become a cooldown type spell like metamorphosis.. but why not keep the tree form? I thought the point of druids was to be shape shifters, if they want to make it a metamorphosis type spell they still can. It doesn't mean they need to take away the original tree form idea. If they want a metamorphosis then add some extra addons to the tree to show it.
They want to give tree form druids more offensive capabilities, but why not just allow them to do it in the tree form? They can make spells allowed in tree form but make it seem as a penalty to use it like rogues using swords to ambush, and druids could be something like -5% damage caused or +5% mana used.
