6. You Play Too Much/Have No Life
Its important to remember, in the bizarre world of online gaming, that anybody more skilful than you should at all times be referred to as a "loser with no life" and anyone worse than you is a "newb." There exists, of course, a golden intermediary somewhere between these two extremes (of playing skilfully but not so much as to demonstrate lack of a social life), which is always exactly the level of whoever is doing the complaining
regardless of his or her skill level. A level 20 in Halo might speak scornfully of the level 25s who spend all their time practising, while a level 30 will treat them with derision. This excuse boils down to simply moving the goal posts if you cant beat someone playing competitively, at least you can feel good about your social life compared to theirs. Its a normal and perfectly natural way to deal with the frustration of losing, but that doesnt make it a valid excuse.
5. Camping Newb
For those who are unaware, a camper is someone who stays in one place for most of the battle, supposedly using their superior position to kill people. Criticising people for doing this during a shoot em up makes about as much sense as criticising tennis players for staying on one side of the net during a match. The basic argument, as I understand it, is that the game flows better if everyone keeps moving thus making it more fun. By the same logic, we should abandon the offside rule in football so that more goals are scored each match. Identifying and holding the strategically key parts of a map is a vital skill in online matches, and if you are unable to do so then youre an inferior player to those that can. Alternatively, you could just expect all players to stop using other fancy tactics like teamwork, and aiming so as to make the game more balanced and therefore fun.
