What would you say if admins of any game tournament add a rule that forbid players to hide their weapon model?


In most FPS games I've ever played (UT Q3 PK and a few others), I used to remove my weapon model.
I believe most players in fast-paced games still do.

I'm still playing FPS games, but slower ones (Source engine based..). Most players now think hiding your weapon model is like cheating.
ESL.eu are talking about adding that kind of rule on DoD Source ; ESL.fr already did.
So what would you say?
