CU has never been fair, the biggest guild always wins. I could imagine that the overall guild size would have to be adapted more to the entire player population. Then we wouldn't have guilds as big as ours. The first step has already been taken, but we now have more players in the guild than should actually be possible.
But it's not fair to only select a few players to participate. So people may not even come in contact with pvp anymore
Or you team up with other guilds
