First of all I want to mention that there have been changes which just didn't think of them at all!
The balance between classes is not good at all and simply it should not be called balance anymore. Why it was not well thought out? You wonder if all the classes are useful in PvP?
Have you implemented Critical Def. Technique, what can to do this scroll? I'll tell you (absorbs critical damage), that is, in short, classes like Strength Avenger become useless and non-existent.
All these for what? Because you can't balance the Predator?
Let's go further, you changed this Power Arena and made the best exp source in the game, but have you considered whether everyone is benefiting from the time you have chosen?
I do not know when things will go well in this game because every time you implement some news simply pathetic!
