my solution to this, is instead of giving everyone more HP! is give a bonus to a class that uses the weapons meant for them, I.E., a class meant to use a staff will get 40% damage increase over weapons they should NOT use, this would keep classes more interested in the weapons they should be using to begin with so Radiants will use staffs, Tempests will use Bludgeons(after skill rebalance) defilers will use staffs?, druid/elem use knuckles saker/mystic will use wand. and for the melee classes, make the they're chosen weapon have benefits for Melee attack as well as skill spam, they already have this system implemented for skills for commanders/assassins/Warlords.
P.S: I.E = In Example, so please just take it for that, an example.
