If you do decide to come back and start playing again I'd really recommend 2-boxing and playing strong duo classes (melee type + healer). This means you'll probably want to avoid int casters, rangers, and rogues. I'd like to advocate for just playing what you enjoy but solo/duo is a big part of this game, whether its doing quests or just farming up platinum, and it can be pretty hard to enjoy the game if you play classes that struggle with doing that.
