Mrshine: after reading your "long" post i have some feedback
Maybe add a maximum amount of people that's allowed to be ranged, like in the EU league if you feel range is a problem. (only range makes you die in melee tho ;P)
I would like the league moving towards active teams rather than clans, mostly because there is only a handfull of clans with enough people to manage a full 8man roster every match. That and the fact it could make more people get engaged in this. =) Just keep in mind people, it kinda sucks that some of us can't be apart of this awesome league that mrshine is organizing just because our clans are semi-active or inactive.
If you don't like people signing up last minute, why not add a 1 week signup period before each match. If you want a new player on your roster, he has to sign up 1 week prior. It could fix the "wait, is he on their team?" feeling that seems to be occuring.
