I've been thinking about this and chewing on it a bit, and....
Fights are going to get harder.

Action economy for 4 members is not going to keep up.

I mean, the minotaurs themselves, if you fight them legit... they wreck you.

But could a 6 man party take the minos?

It changes things, doesn't it? having those two extra rez bots?

Anyway. My final thought, after hitting 100 hours. 6 person is the way to go.

Maybe it will be added when more party members are available to choose from.
