It's better to buff all classes in the point where it's hard to pick what Class you're going to choose because all of them are so damn powerful, by then no one can complain about unbalance skill, unbalance class, unbalance fanction because if all Classes are op then this is going to how to build better equipment, how to use unique fighting style, which skill you are going to use, and how to improve the skill combo, compare to nerfing all Classes just because of majority of players who want their Class to become op and nerf the enemy side.
Developers should change their mindset about how to satisfy the players.
