Hopefully Bioware will incorporate this superior ranking method for 5v5 rankings. Each unique team of 5 players that play together constitute a new team for ranking purposes to follow the method outlined below.
The r2sports method works best. Team A challenges Team B and gets Team B's Tracking Number. When Team A beats Team B again or a team above Team B they move ahead of Team B. It's very dynamic. The ELO system is too slow. All sports are now ranked according the r2sports method as I have just described. So should it be with Generals 2. The only change I would make is the top 50 teams are required to play at least one team within 50 rungs below them per day and if they don't, they move down 2 slots. This prevents teams from avoiding challengers to try to maintain their ranking.
