If you beat someone, regardless of what you look like, you outplayed the person. Blaming a loss just because you "didn't know what kind of gear they had, or how geared they were" is a pathetic excuse.
I hate to bring it up, but WoW had the whole transmog feature in PvP and... well... no one ever complained about it being an advantage.

Yoshi is so caught up on making PvP so carebare fair for everyone little things like this irritate me.

But what about not knowing what class you're up against?
I'm glad the whole Fresh Meat thing was removed and instead replaced with the actual class name.
<WHITE MAGE> is a White Mage and nothing else. No confusion.
Or, at the very extreme, look at the weapon they are carrying.

Yeah, hate on me all you want. Call me a cheater/unfair for wanting this in.
But if I wanna fight in a bikini, then by God should I have the right to do so.
