Hi, I've been trying out the game and I like it a lot so far. Combat is fun, and all the classes seem really cool. However, I do have a couple of suggestions you might consider.
I feel like there are plenty of quests in the game right now, but the amount of xp they give is not enough to level up on. This makes it necessary to grind, which I personally don't mind but a lot of potential players would be turned off by it. Adding more quests would be unnecessary and time-consuming for you, so it would probably be easier to increase the amount of experience awarded for completing quests.
I've noticed that Paladins have two abilities named Fanaticism - an aura and a passive skill. My other suggestion would be to change the name of one of them to Zeal or something similar. That way players won't confuse the two abilities.
