If you don't know how to play domination, then don't play it. It's not that hard... It is so incredibly stupid to cap all 3 flags. Unless you're down by a large margin and really need to catch up, then NEVER cap 3 flags.
Oh well, at least I have 2 EMPs today... almost a 3rd but just as I was calling it in the game ended. The guy's finger was a couple pixels away from pressing the button.
