All class ini this game have 2 even 3 super armor work in the arena. Raven only have 2 super armor avaliable at arena and you just took 1.... Whats wrong with you developer.
Raven also have the most low hp recover skill.
At least buff her hp recover skill and move her super armor at arena to another skill...
That was fucking unbalance

Raven was unbalanced, It deserved that Nerf.

She had the lowest hp recover skill rather than all class in this game. Thats why she deserve get that advantages, unless developer buff her hp recover skill. That would be difference
