I do agree that there are a lot of things that piss me off, however I don't consider them as cheap/hacks. I believe that if it works, good for you! People need to learn that there is usually a way around a "cheap" tactic if you look hard enough. but I can't say I do not find some tactics as annoying. Camping, akimbo shotguns, when the game spawns you right next to an enemy, noob-tube, rocket launchers (when used just to get easy explosive kills), lunging-knife kills (when he's too far away for a knife kill to be possible but it happens anyway), and when calling hacks are the only excuse people have for sucking. And that's just naming a few things that really aggravate me! All in all, tactics are NOT "cheap" because they are too effective and require no skill, they are "cheap" because they just annoy people who use ACTUAL skill in the game.
