People take this game way to serious. I know people that when loosing a vs get annoying as fuck and start to throw accusation here and there about using big pots weapon defense hacks etc, etc.
And if you dont take their side and say yes the only way he could beat you is by not doing it legal, omg then you are the enemy too jajajajaja.
I dont care much about being the best, honestly how good of a feeling can it be to consider yourself the best ?
After all, that would just mean that you have sitted on your ass long enough to be extremely fast and accurate at pressing no more than 12 buttons on your keyboard.
And to answer your ego question, too many shy little nerds play this game. They feel secure and big behind their screens, items and 1337 combo skills. Its allways funny though, to see the ego idiot loose. Allways an excuse to why it happened.
