We got an old man healer, an elven swordswoman, an orc rouge/tactician, a hybrid brawler, and a succubus mage/debuffer. We got this.
I assume I'm going to be the tank considering my material form is a shield, so I think we're balanced. 4 dps and 1 tank/healer will be  good, but you guys will pretty much have to babysit Samuel for him to be useful.
