Have you tried DC universe online it has alot of classes, a very high player base, a very good tutorial, really good pvp and pve. Give it a shot.
The classes are called powers there is 10 to choose from fire, ice, earth, light, gadgets, mental, lightning, nature, and sorcery and after you pick your power you choose what fighting style you want there is 10 to choose form 11 with the next update coming sometime this month. The fighting styles are one-handed, two-handed, hand blasts, dual wield, pole arm, bow, dual pistols, rifle, martial arts, brawaler,and with the next update shield.
I have just checked them out on the list.
