I always enjoyed fighting Bish far more then Rooks so when I came back two tours ago and the Bish numbers were down in the dumpper, I sucked it up and went Bish. As a Knight, I'd usually ignore the Rook front unless I wanted a bomber run, then you can usually count on a few guys to come up and fight. In a fighter I'd much rather fight with or against the Bish in the weeds.
One big surprise I got as a Bish was how many Rooks will fly against them under 10k. That never happened to me when flying Knights. Last night I actually had a whole series of fun fights on the deck with three Rooks trying to take a Bish base. Lasted around two hours, best fun I've had in a long time.
