Hello. I am a druid. A suggestion of this sort essentially ruins my class. Most classes can do without won and take focus instead. My hp buff is subpar so a cleric will be around instead, because lets face it - Who DOESNT want Aego? (If you say you don't, you're stupid). In a 2 healer situation, Focus is almost always going to be more beneficial. Currently I even use focus in most situations.
My ds can be replaced by bringing a mage for ds. My resist buff is ok, I guess, but lots of stuff cant be resisted anymore. My heals are not as good or efficient as a clerics. My dps is not as good or efficient as a clerics.
Essentially, really, the amount of rebalancing this would take is beyond absurd. I mean, just between Sanctum, Spires, Turuj, and the few high end 6 mans that I've been doing since I've been back, they're all balanced 100% around having every buff, give or take a mana regen buff that can be swapped somewhere else. Everything is so tightly tuned. Tuning, for example, Xi'Valla or Gloom around not having a JB in a group, or having JB in a group, is, hands down, absurdly ridiculous to even attempt. Then you have all the group exp content, questing that can be done with smaller groups/duos, and duo farming stuff.
36 man to 18 man was a positive change for the server. This buff stuff, not so much. Sure spending 15 minutes buffing a group is awful, but balancing for the different group possibilities is just an impossibly hard task that I can't imagine ever happening.
