First off for an FC, returns should not be a factor on how good they are, and tbh the entire idea of basing it off of stats is ridiculous, but since we've already started I'll contribute.
Bully you also need to bring into account the amount of warsongs played when comparing yourself to other FC's
EG. I have played 147 games of warsong gulch, and capped 287 flags. So we divide the capped flags by the number of games, and my average of caps per game is at about 1.95 flags per game.
In your case, you've played 198 games of warsong gulch, and capped 266 flags, so your average cap per game ratio would be about 1.34 flags per game.
Again there are a lot of issues with determining the quality of a player based on this (Such as a person who plays one warsong and caps 3 times, and then has a ratio of 3 caps per game.) but since numbers were brought up, I thought I'd contribute
