I am the guild leader of a 209m GP guild which has mandatory TW participation. As a result of this we usually have 50/50 and we routinely face opponents who are 230m+ who have only 44 or 45 members sign up. The TW match making system has resulted in many competitive guilds intentionally sitting out players to be matched with weaker guilds. Our opponents this round had an average player GP of 4.67 to our 4.18.
Match guilds based on their total GP and not active GP. It should be our responsibility to get our members to sign up. If our members dont sign up and we lose, that's on us. We have players who will be busy/away on TW just post more on defense.
We should be penalized for poor participation, not perfect participation.
