Hello. I'm new to this game. I did not find a text or article saying the diference between cla**es.
Could anyone help me with that please?

Right now there are no differences between cla**es, exept the background behind your items. The cla**es you can choose from now is relatively new. But keep your eyes open here on the forum for updates. The moderator and some of the admins are working hard for our future pleasure

I'm working on it

It shouldn't be more than a week before something changes.
