Stamina = Damage Increase (revamp)
and same design for mana
I think this would make stamina a more desirable asset to have if it meant that it correlated to one's damage sense nobody ever completely runs out of it.
For example base stamina for barb lets say is
4000 = 100% damage
with stamina gear = 6000 = +50% damage increase
when 4000 stamina is used = 2000 pool stamina = -50% damage
I think it would be a rather cool adjustment.
It means that I would actually start using stamina pots again in minigames and tools that remove stamina (e.g. boneshatter)actually have a purpose again and things that give stamina (e.g. predatory instincts) also have a reason for usage again.
Also I think it would be cool when you start seeing ppl actually thing about what combos or spells they use because they don't want to loose damage so they save all their big mana/stamina for the burst when they need it. This would really change things for the better in aoc pvp minigames/sieges.
