I might be mistaken (English lessons in school are long ago and I never really payed attention), but if "Who" is referring to "The horde" (which you seem to imply), shouldn't it be reading "Which"? 
The who I'm referring to is an entity, the Bish, then Rooks. So no it would not be which. It would be which if we were saying which one wins more. What I did though, was to forget to insert a ? instead of a periold, should have read; Who wins all the maps?
Idk if you have the stats on that, but I bet its about 64% Bish, 34% Rooks and 2% Knight.
The above aspect is one that I don't really care about, I don't have enough time anymore to fly to win the map or even make much of a contribution. When I can, I'm logging in to get into a good scrap. But I will say the above is not a good thing for new blood. I started as Bish and it was impossible to get a kill flying with the horde, they're too quick, and yes gents, not all of the horde lawndarts, some get a lot of kills. Anyhow I switched to Rooks and found it was a great place, and a lot of great people, but a few that also really stink the place up, but many there willing to help me/others learn. My affinity toward Luft ac lead me to Knights where I discovered there is almost no organization and nearly everyone does what they feel like. Anyhow, my point here is that:
^ that stat is a turnoff for new blood, imo.
Nobody really seems to actually care though so
MERRY CHRISTMAS! Things will remain the same, until they don't.
