My first character is going to be a Tiefling Light Cleric of Ilmater in a multiplayer campaign with some friends. I haven't played Early Access, so I don't know how deep the roleplaying opportunities are, but I like the idea of juxtaposition between self-sacrifice and self-hatred.
I'm a big fan of Paladins but want to save that playthrough for non-multiplayer to avoid the oaths causing problems. And I know I'll want to do an evil playthrough at some point, but haven't decided what I want to play for that yet (Drow Rogue? Shadow Monk? Spore Druid? Warlock? Or maybe a Dragonborn Sorcerer? I want to play everything).
