Yes, I agree that 6 Chanter may not be the ideal power group in fact, and mixing in some Paladins (and perhaps a Priest and a Wizard for buffs/CC) might be a better path. I would probably run 3 Chanter, 1 Paladin, 1 Priest, 1 Wizard or 2 Chanter, 2 Paladin, 1 Priest, 1 Wizard group the next run.
Fantastic opinions here! I'm going to give it a shot after this playthrough. I guess #4 will be a godlike rush. After so many pushes though and so many loading screens, I deserve myself some "desert"! Haha.
Thanks for yalls replies!
