Okay, since I'm a GM here, I'm going to make a proposition:
It seems that everyone is casting opinion based on nothing that's been proven as of yet. Some people feel it would be good without knowing if the quality would suffer. Some people feel it would be bad without knowing if the RPG would improve.
So, I say we only do it for a trial basis. Nothing more, nothing less. If people like it, we'll keep it. If they don't, we don't do it anymore, and the RPG goes back to the way it is now.
I'm not saying this out of bias. twy gave me the go ahead, since I'm playing Superman only until LT returns, to keep Nightwing aswell, so it's a non-issue for me now. I'm doing this because I want to be fair to everyone else, because I don't feel right doing it when other people obviously want two characters.
But rather than make the rule an official rule, due to my position, I'm offering this to side with the people against it, aswell. I don't want to come off as an ass to anyone... I never have wanted to.
Anyway... What do you guys think? Trial-Basis... Sound plauseable?
