I see what you mean. Good point. It's not so much about the damage increase, but that the slot could be filled with a potentially skilled solo player who would contribute more to get the team to win. I gotcha.

I'm thinking about just doing 4 shaman and my girlfriend play paladin and level w/ me and heal. Then I'll have a 5 group for something fun, maybe 5 boomkin? And my 3rd group is going to be a PvE leveling/farming/professions combo.

I'm sure this is going to change 100 times before the end of the day, but that's my general plan right now haha.
