You are so increadibly wrong with that statement. Im not gonna go into a EU vs. NA discussion as that would be increadibly pointless and simply isnt something one should go into, not even a fat and arrogant robot....
I don't know about the whole scamming because you act like a girl/are a girl thing. At least for me, i don't give a damn wether im playing with a Girl or a Guy. I treat them the same, as a fellow gamer. In the end it only comes down to how good they play in my party and for that it doesn't make a difference.
I guess others might act different but meh, thats them and this is me.
Usually I end up playing females characters but not because im trying to act like a girl (Wich i certently can't ^^) but simply because I prefer the animations and looks of them and hey, im a guy, I like to look at a pretty Char ;)
On the actual topic:
For the most classes, I guess after reading this thead I think BM might be the most played class as well. They are just pretty cool with awesome skills and stuff, at least in PvE they are really fun to play (Even with my huge Korean delay im having a lot of fun with them).
