The Cleric is a pure healing class, plain and simple. They offer no special buffs, no unique utility, they just have very powerful heals. That is what makes their class, and that will always be their design. They are a heavily armored healer that has an emphasis on long warmups. The moment the receive special party buffs or unique abilities that aren't related to healing, they become too powerful, and in my opinion, it breaks their design.
Wait up here a second, Delf. Why would things like wisdom, might, accelerando, etc. break their design? Those are group buffs that effect every class equally. 80% faster mana regen, 20 or 25% physical damage, and speed buffs. If anything I'd like to see a 20-25% SKILL damage ability, 80% faster stamina regen, and we already have excavate. That would balance the system by buffing every aspect of every class in a party, and that is THE "Support" role.. is it not?
Perhaps here, you could give a few select support classes the skill-dmg buff ability, and a faster stamina regen ability. Also, I'd like to complain that Wisdom doesn't change how fast you regen, it changes how much you regen. (I go from 7 or 8 per tick to 12 per tick. The 'tick rate' doesn't change though.) I think it would be cool to see that instead.. if possible. It would be nicer to cast sooner than rely on discrepencies on when you regenerate mana every so often. For example if I was at 19 mana waiting to get 25 for my next fireball, and I died in that 5 second window or w/e it is because I was unable to cast it, due to the fact that my mana isn't going 19 20 21 22 23 24 real fast, instead it's just 19.........wait.......25........wait.......32...... it is slow. Also, wisdom incorrectly states how much it helps...
7 mp5 + (0.8 x 7)=5.6 = 12.6 mp5.
As far as I can tell, I don't get to see that .6 but I would have to test it better to see if every other tick adds another 1 point of mana. (1.2) then test it on the 3rd tick after that to see if its (1.4) then the next tick after that to see if its 2.0, etc. IDK, I just feel it's kind of imba. I wish mana regen was fluid.
