I have to be completely honest.... I don't like any of the current options. Not one of them fits with the persona I have for my characters. But hey, I am picky in game just like in real life. As for the current options I am really not a fan of them as adventure partners either. I sincerly hope that Larian introduces a few more options before the end of the first act or I may end up soloing beyond that. We seriously need another thief, fighter, and cleric options that don't make me want to kill them after first meeting them. Heck.. that Zent halfling merchant in goblin town has a more practical and amenable personality than the ones we got thrown in with. Now she might make an excellent thief companion or lover.
