Maybe add more skills to ech class, cuz right now at lvl 9, the buffs for each class increase by like insane amount percentage per level from 6.
think about it, evasion can give like 40 dodge at level 6 for example, it increases then at like 5 more per level so 55 dodge.
but now u have taunt which can be stack 2 times and that dodge % also increase with level
