Too each their own. Now, I will say the first time I saw someone use an actual person as an Face Claim instead of an art piece it struck me as odd as well. Then again, thinking way back seeing someone use an art piece for a face claim did the same. Now today I will use a person or an art piece as a face claim and not even think twice on it. It's just a visual representation of the characters appearance, not the characters personality or background. 

	Having said that, I have seen it done full out. Back in the WinMx chat days some nearly twenty years ago I saw people playing celebrity couples they wanted to RP - that struck me as really odd. To this day I still don't get it. Face Claim is one thing to create a character, but to say these days you are Jay Z and Beyonce? Yeah, I just cannot wrap my mind around that. I get cannon characters, I don't get the rest but I guess technically it is the next progression just doubt it would be something I could ever do and feel okay about. Some lines I just prefer not to cross. Who knows in another twenty years though. (Though by then god only knows how virtual reality will be used in RP - oh god the thought just gave me the creeps. Excuse me while I go bleach my brain.)
