Eh Talk to Lugu about it, wasn't my call. I will say this though, in a roleplay, something without stats or crunching numbers really. There isn't much of a difficulty. There is a conversation, relationship between the players and whoever is playing the antagonist. Saying it's easier to cooperate with five people is similar as me saying it's unfair for one semblance to be stronger than another and all that. There's hardly a game to break. Either way, I'm no GM so talk to him about it.
