Pointless and too much work. Remember that this is about fun, not something that people would be dead serious about. Also do I need to remind you about the fact that most of us are playing on usa servers almost daily and are more than capable of handle those high pings(ofcos americans are in win/win situation, but who the *dance* cares?). If captains do want to win and be serious about this, ofcos they will pick more low pingers for those positions which beneficts from it the most and it's very wise to do so, but as long as information doesn't transfer instantly all over the world and back, or we can't get our asses over the same place and play in LAN, we do need to find simple solutions. After all at this point it's all about the event, not about who has the best odds to win.
I don't consider 5 americans with 3 high pingers vs 4 euro, 2 asian and 2 american team unfair if played on american server... We all know what euros have done to american "top" teams in the past on american servers. No brag, but just simple reminder, that ping is not THAT important.
