It really comes down to this, for some reason more people CHOOSE to fly Rooks. Whether it be for the numbers advantge or because perhaps flying for Knights and Bish is not as much their cup of tea. Regardless the reason, HiTech has decidied to penalize us for this.
I think the only way to solve the numbers imbalance is get the Bish/Knits to make flying for their "country" more inticing.
Its obvious that droves of players from the Knights and the Bishops have no problem country switching or leaving without any hesitation. I and many other Rooks, in contrast, have no desire to leave Rooks.
But hey, its the 21st century, lets put the blame where it really belongs. Knights and Bish cannot keep up with the numbers of the Rooks, so it must be the Rooks fault, penalize the Rooks.
