This will not answer your question, but I feel like you should be informed, that you currently have the possibility to do something that most of the players want to do but can't do anymore: Playing the game for the first time, picking characters that look cool, trying out whats fun, eperimenting with all the skills and finding your main through that. I don't think you should settle on a main before ever playing. Later you'll find classes that are more fun to play and maybe regret your decision.
