May I repeat you are still a noob for saying that because
1. Everyone wirh a little experience knows that raider, warden, conqueror and berserker are considered some of the best duelists, while the gladiator, centurion, tiandi and highlander all suffer from crippling weaknesses.
2. Every character is unlockable from ingame currency, the amount needed collectable in 1 week of casual/two weeks of noob playthrough.
At least take 5 seconds to think before complaining, the feeling might be strange for first, but you might find some real issues to complain about.
