It's kind of crazy to need 100 wins just to be able to decide you want to play a different class for PvP. I'd rather you were able to have different PvP abilities per class, but even then it would be better to do a reset with seals rather than marks.

This would be super demoralizing if you end up not being very good at the job you already bought abilities for. Or whatever job you originally picked gets balanced so much in a future update you don't like the play style of it anymore. Or you're just sick of playing that job because hey you've done like 500-1,000 matches with it. Then you're either on a job you don't want to play anymore trying to get 100 wins so you can switch, or on a job with no warwolf gear or abilities as a relatively (or very) high rank probably going against other high ranks who have tons of abilities and gear. Yay!
