they were split because of poor game play... much like what goes on on Tuesdays.
Odd, I've always found more fights, to more people's tastes, in the bigger, more populated arenas. If you want base capture, it's there. Furballs? Yep! CV fights...guaranteed. Tank battles, also there. "poor" gameplay was never mentioned. I need a definition for that, actually.
Some folks have mentioned on the boards that they can't stand the big fights because it lags out their PC's; their gameplay suffers due to hardware issues. In fact, I've heard the same things talking over voice chat or text; some people refuse to participate in crowded fights because of a negative PC/Internet performance impact. I've been graced with a decent connection and a good machine for most of my gaming career, so I can't comment on the validity of the arguement that older machines or slow connections aren't much fun to play on in busier areas.
