Fear of playing a DPS

[Mitsubashi]

It's harder to be good at DPS than it is to tank or heal. There's a reason SE don't allow DPS meters and it's that most DPS players are not good at what they are trying to do.

Tanking is very easy. Healing has a lot of responsibility but it isn't hard. What is hard is optimising your rotations while dealing with boss mechanics.

It sounds like you would enjoy the role of healer or tank more than DD (damage dealer). I find that the damage dealers usually have more complicated rotations than healers or tanks, (not to say that healer or tanks arn't complicated, just different) and that is one of the reasons I like playing them. I also like to see big crits and know I'm smacking the boss good.

As for which dps you should pick, I would recommend unlocking the classes you want to play, and then trying them out in Palace of the Dead. You can get a basic preview of what the class is going to play like; (although due to them removing abilities and adding new ones you wont fully know how the class plays until level 80) This differs with some classes having most of their toolkit at an earlier level than others.
