Explain, please, how this counters class homogenization. I see it forcing all druids to walk a very narrow path. We will all be shapeshifting situational healer-dps-tank-kins. The diversification by specialization allowed by the current talent trees will be completely lost in the new blended 4.3 talent bush.
Understanding the desire to only play one role as a Druid is no different than playing one role as a Paladin, Priest, or Warrior. I am a healer, I enjoy healing, therefore I am a tree. I can be a cat for a quick attack in PvP, fly to where I need to go as a big blue bird, but my focus is on healing. Blizz made some progress towards homogenization when they allowed trees to cast Wrath in treeform (but that was far enough for me:)

My GM loves to tank. His main is a Paladin with 2 tank specs. Should he be forced to use holy abilities to be a good tank? Maybe drop his shield for some quick 2 hand damage? Should our Shadow Priest be forced to heal because "...well, yanno, he IS a Priest"

Do you want to see your gear when fighting? Perhaps you shouldn't have rolled a class that changes shape (Druid) to do ANYTHING, one that takes on Shadowform (Priest) or one that relies on stealth (Rogue). The fact that my toon gets branches waving when throwing heals tickles the hell out of me and is just a huge added bonus. I still see my gear when treeform is on cooldown but I see no difference in maintaining tree or Moonkin form just as a Shadowpriest stays in evil-blue-cloudform.
