Because when you shoot any gun, the bullets spread exactly like a tf2 heavy gun, because all animations, skins, textures, voices. (radio chat etc), movement etc. is a direct rip from tf2. Because instead of fun, competitive pub play it's infested with hacks, inspired by useless ranks in MM, and because lots of people care more for their faggoty-assed hello kitty gun then having fun. CS and the fun, competitive gameplay that it brought is dead. I don't know what GO is - other than a money-maker for valve - but it's not CS. Couldn't be further from it.
I'm not opposed to change, I've been a cs-lover from the first beta - i even loved source. But I'm not 12, i won't give valve my real money for fake, digital, useless and meaningless skins. I don't care for it. I want good mechanics and good-looking textures etc. But nope, it looks worse than any cs has looked and has _by far_ the worst mechanics I've ever witnessed in a shooting game. I would rather play COD.
