-What method do you use to calculate ELO?

-How much ELO you're losing after defeat?
Depends on your ELO and ELO of your oponent. If you're going to win against low ELO oponent you won't gain as much as someone with your ELO, but if you're going to lose against low ELO oponent you'll lose a nice chunk of your ELO.
-What's starting ELO?
-What matches will be taken into the raiting?
Tournament matches only and if both teams will agree to play for a ranking points.
-Can you give us a lil sneak peek?
If every team will provide screenshots from every map, yeah it's possible, but I'll have to think how to calculate it. Tournament matches only of course. So far I vouch this idea up-Do skirmish clan matches count towards individual elo?
-How much ELO you need to get into the raiting?
Well do not really know that yet, for now I'll post every participant.
Feel free to ask any questions here or on PM and I'll put them here soon™
