I'm still going on the tacit assumption that the WoB 'Mechs are included in the CC RATs but not the FWL's due to the WoB's efforts to conceal their level of preparations for their Jihad. (Which was initially aimed at the Clans.)
To be honest, during the main development phase of the '58-'67 time period, while there may have been a FWL team at conventions, there were very few dedicated FWL fans among the players I most often interacted with.
We mostly gravitated, first, to FC, who generally served as the 'intro' faction and was where most noobs got their training. Then, players would migrate over to DC, in ones and twos, until there was an acceptable parity of numbers between the two.
CC was composed of a small number of clued pilots who were very active and generally were the first ones to gain pilot and, especially, gunnery level-ups which would consolidate that exclusive elite status.
FWL, in most cases, was a group of largely unknowns who rarely had a decisive affect on the scenarios and who's value was often played out as a spoiler or perhaps a possible temporary ally.
When the number of active players began to decline and scenarios more often became 1 faction vs 1 faction, FWL was the first to go, followed by CC.
To my knowledge, what RATs we used were custom made to ensure balance.
