Try mages, thieves, warriors, pirates or archers. I hear they're fun.

I suggest picking a class that you have random decent equips for. I got a 100% tier up thief overall, so I went and made a shadower. It helps give you some motivation to lvl the class. Another thing you could do is scroll equips from each class (100% 's ) then ee (regular, not advanced) them and the last one to not break is your class. Cause really all classes can be fun at one point.

I enjoy playing my DK.

My two favorite classes, are xenon and buccaneer, both are pretty op (even after xenon got its nerf) Luminous are really good, (but all top 5 are all lumi's right now)

It's pretty subjective, but I really enjoy
