I don't know anything about ELO ranking system but I like ranking systems so I guess I like the idea!

I'd like to see stats from frontlines, stats for each class, like average kills, average damage, kda. I love frontlines and play it as much as I can and these stats would make it more fun. Maybe stats like highest damage in a game and highest kills in a game, and yeah there are lots of options.

But I guess its the ps3 limitations thats stopping this?
