Personally, I disagree with it. Simply because half the fun of playing a real-life wrestler is their backstory, mannerisms and the entire lore surrounding that character. This, when applied to a fed with a mixture of the two, really makes it hard to reconcile. It would make little sense for a fresh wrestler to match up against The Rock for instance.

It would also hurt my soul to see a The Rock lose trash-talk battles.

However, I do think exceptions can be made in that it requires GM/Admin permission before a real-life wrestler is allowed. This would guarantee that the handler handling him is known to be responsible, and has the ability to use the wrestler of his choice. I don't think we should do any policing as a fed, but the admins regulating it makes sense to me.
