*sigh* No one asked anyone NOT to play anymore. It's completely your decision, and your decision alone, as to what you want to do in-game. Granted, it couldn't hurt to help someone out if they ask for help, and if you are more than capable of providing tips, you should do so. However, you have to realize that there will be people like that, and people who aren't like that. I, for one, will let you own me 6 ways from Sunday and not ask how you do it, but if you were to take on someone else and they ask you for some pointers, what's the harm in sharing a few? If you pride yourself on not "HOWing", or beamspammming, why not fire off a few tips how to avoid doing that? No one expects you to stop playing seriously or competitively to teach people how to play ESF 24/7.
And, no, no one expects you to stop playing ESF when you are better than most others, as I said, it's really your choice alone as to what you want to do in a server. Nothing can change that. However, there is never a need, in any situation, to develop a chip on your shoulder when you are a really good player, it just doesn't help you at all, and it will actually get you a harder time finding people to play against, I find.
