I'm glad someone else mentioned this. I was in the MAW for a few weeks and after seeing the Rooks pummeled repeatedly, sorely outnumbered, I jumped to their side. With my limited play hours, I think I played a total of 3 nights, maybe 4 hours. After seeing that the Rooks were regaining some numbers, I went back to Knits to fly with my friends. Well, I'm no longer allowed back in with the MAW since I did such a traitorous act (changing sides...) and while I see their point, I also think its somewhat silly.
But, their rules...I'll just roll my eyes and move on, flying for me, myself and i again.
Quite honestly, I think what I did, and others did, was quite sportsmanlike, trying to balance out a hugely unbalanced arena.
