are skins used in "comp" in CSGO btw?
Yes they are. Changes nothing about the game other than "skins means skill" ...
how could there by a "competitive" scene in CSGO with all those skins flying around?
Mate, have you even played CS:GO? Because the skins hardly look ridiculous like those "cool" hats in tf2.
That's why CS:GO is a serious game, which is played by serious people who have serious skill while tf2 is a ridiculous, fun game, played by people who aren't wanting to play a serious game.
