There's a few classes I've not unlocked and/or even got above 50 yet, but I'll put my piece down anyway.

Dancer has to be by far one of the most basic and simplistic classes I've seen in any game ever, you literally just press 1 and 2 and hope that the 50% proc kicks in for either of them, and then further hope that you get the next 50% proc to use your next attack, you will then use your dance to buff and forget for your team mate while scoring some decent damage, and then it's back to pressing 1 and 2 and hoping for procs, the animations are nice, but dear god what a boring class.
