Alright then, I'll give you the moral of the story.
The point is, firstly, don't blame other people for sucking.
Secondly, if they are lagging a bit, deal with it. Nobody likes a whinger, and furthermore, the lag is probably affecting them as much as it's affecting you. If you can't fight someone who lags slightly, learn to do it. You'll find one day that you lag for no reason at all, and if everybody whines at you for it and refuses to fight, nobody will have fun.
Thirdly, if they're lagging a lot and are absolutely impossible to deal with, bow out and do something else. If you choose not to, that's your choice. So what you "lose", you don't even explode.
And why it's here? I saw this all the time when I was playing, people whining about me, or people whining about others. In a few cases, I saw something like this, where people were whining about lag when there was none. Yes, people like to protect their egos, this is true. But, I really feel, factions should be setting the example, rather than blending in with the crowd.
