Although you are right you are also rong,
Classes are not balanced, for example take 1 class , archer
- you have:
-range atak.
- aoe/ multiple skils, small skils cooldown
- jumping skills/ hiding skills
-also bow has big P.atak, so you give alo to p.atak with multiple skils
- also, you can max atack speed very fast.
In the past aoe where the mele class not range class, with is logical. Did you see 1 archer kill 3 target with 3 arrow? But you can kill 3 target with a big wapons if you are melee.
So some class are privileged and other are not.
You can evolve unlimited with archer, but you can not with other class.
Also you consider archer having the same skills cooldown and atack speed as dagger class? And why one have aoe and the other not?
Archer and dagger are both single target class , one range , one melee, one has small atack speed, one fast atak speed, one can jump becuse it is melee the one can not becuse it is range. None of this apply now.
Mage and mele class where aoe.
