The worst thing in gaming is the increased competition with unknowns, you find people doing whatever they can to win yet at the same time take the fun out of the game. A good example would be One Man Army + Noob tubes, I've won many a 1-2 bar games using this kit with a nuke, because dem dere Americans were shit talking me for being a New Zealander. There's no fun in using the kit, and it makes the game too easy to bother playing properly if there's someone like that one the enemy team. Another (CoD) example would being the FAMAS/74u in Black Ops, really boring guns, really easy, you know...
