Rift

[Super Buu]

All the archetypes are pretty obvious in what they specialize in (I mean, you've played other MMOs so warrior, mage, cleric, rogue should be straightforward enough) and you can respec your souls infinitely so just go with whatever you feel like. Cleric does seem more tanky than in other games as they have chainmail which is better than rogue gear (leather). Personally I wanted to be a warrior mage for my main, so I went warrior archetype with riftblade as my main soul and champion as my second for more two-handery berserkery goodness. Beastmaster as my third for a free kitty =D.
