I'd agree with pretty much all of this. I think a party of misfits can work without a straight man though that archetype definitely makes it work better. Maybe it's forthcoming.
One thing that personally annoys me is the evil characters are so far into chaotic stupid territory I can't see them being played by more than a tiny minority of players. If you only have 9 characters why have 3+ that are almost entirely impossible to work with?
Also having an option to romance Shadowheart when she comes across as a special needs child is pretty creepy.
How in the...How did you come to the conclusion that Shadowheart comes across as a special needs child?
