ccvi, I doubt there is anything more that we can do, or ask of.
I do not know if it is the effect of the new perk system, but for about a week now, in the times that I logged on, I had some pleasant experiences of us Rooks being the largest country around. Other times we were outnumbered, but only marginally like 10~20 people. That's a fair game.
According to situations, and the way the terrain is designed, one country always receives a combined attack from the other two from time to time. I don't think there's any sort of conspiracy or tendency for the other two to gang up on the Rooks. Sometimes we team up with Knits and bang Bish, other times we team up with Bish and bang the Knits.
.. since I more often than not find our numbers our in par with the other two after 1.1, the gangbangs don't concern me much.
