We've made the server retail-like and therefore all the skills and classes work as intended by the game creators. For some players it is easy to play, for others not, or just depending on the class.
All the classes are balanced to some extent, meaning having the plusses and minuses, opposite classes.
I'm sorry if some things can be inconvenient for you, but we are not going to change any class balance. The players come here to enjoy unchanged aion, plus the point of the server to provide the untouched game.
