I think it's a bit more complicated than that. Currently participating in an empty or underfilled fray penalizes a players ability to contribute to their guild as well as someone just entering a fray with heavy participation. I feel this personally when I do something like play in a Gold Level CL + RB Fray and only 4 or 5 people sign up. I may win all 4 or 5 matches, but I would score more points for guild in a fray with 10 participants. It currently penalizes players that do show up with a valid deck because other people didn't show up.

Anyway I digress, I have been asked to deliver this message from the author:
