Well, this would be the best xpack for it. With 3 hour lockout timers it makes it less painfull to get a fail group. It is worth it to stumble through with a subpar group than sit around trying to cherry pick a group together. It's not like you ruin the instance for a whole day anymore.
I still love that they pretty much said it was their intention for it to make 'atypical' groups. When I hear that though it sounds like they just didn't want to bother making it properly filter classes.
