Why do we have two threads of the same topic? Well anyways, what hasn't been said about quickscoping? It's simply not sniping and it takes advantage of the high power of sniper rifles so you can use it as an assault weapon. This shouldn't be the case, snipers should be snipers, domination in long range, weak in short range.
In comparison to noobtubers, I respect quickscopers more than noobtubers because at least for quickscoping, you gotta sit down for a few hours and learn how to do as opposed to just pressing a button and getting several kills. But it's basically exploiting the stupidity of the developers, and I don't have much respect for that. I'm rather getting tired of hearing people saying "Just because it's in the game, it's legitimate", because it isn't. If the developers released some sort of aimbot or ability to get "under the map" if you were last prestige or some instant "I win" button when you've gotten 25 nukes and they say that it was intentional, would you say that it's fair since it's part of the game?
If you've ever played "Gunz: The Duel", you will know that in that game, the entire gameplay revolves around an exploit that allows you shoot rocket launchers almost instantly and basically kill you in less time than it takes you to process what happens. The community in that game claims it's part of the game when the developers haven't acknowledged it and the community practically goes berserk over anyone that says otherwise.
