Oh man, I've seen this kind of thing before. I've also seen the "just house rules it" approach.
That's the sign of a sinking ship that needs to be righted quick.
I'm not saying this because I want it to happen or to be all negative Nancy, but again: I've been through this before with another game. Once you start having to put limits on things yourself it can get frustrating for other players just like it's frustrating for you. Then the circle spins on until no one wants to play.
If this is getting commonplace, FFG needs to take a serious look at it
