If you've been playing on the GON server for more than a day, then it is very easy to know who is who. If you see someone come on with a ridiculous face, stupid name and a very specific ping, then you know exactly who it is. The newbies wouldn't know who is who, but they would be too crap to stand a chance anyways. And besides, if you see someone that looks like a camel running towards you, chances are it's a veteran of the community and they would probably beat you anyway. Not too sure who they are trying to "confuse".
Yes, everyone slings abuse once in a while and many people play under aliases, KEEN are not the only ones guilty of that. And if people are slinging abuse at you and you feel insulted by it, then you are a fool. This is the internet and if you can't take the occasional insult from an idiot, then go live in a cave.
Yes, KEEN are very good players. Yes, they will probably beat you. But, there are a handful in the community who are nearly as good as them. If people are complaining that KEEN are too good, then play the bloody game more.
I don't believe they are hated. It's not their fault that they want in on scrims, with better players, instead of destroying noobs in pub.
Who hates their aliases? I find them funny.
Atleast they actually play the game. I don't see people complaining about many of the people in mumble. They go en-masse to the server, completely naked with no weapons, which often results in their team being destroyed.
The only people who are having a go at KEEN here, it seems, are the people who have shared bad blood with them since beta.
Edit: Oh and NN, there is a big difference between World War 2 and a childrens computer game.
