Not sure what to think.
I only know (by the roster only) that on Tuesday night before Dickweeds squad night, I believe I observed a total of 53 Knits & Rooks combined, and 11 Bish.
I also observed that for most of my 2.5 to three hour B29 flight, there were only limited, short instances of Rooks and Knits developing any activity with each other according to map activity.
Most of the activity, if not very close to all activity was against the 11 Bish roster.
I did not factor in AFK/in flight, etc, etc, etc...
Not very analytical, but alas, there's my two taxed cents.
