The squadron mechanics were there to introduce an ultimate victory. Ordinary players could join to different sessions or different scenarios under a single session. And asymmetry was a bit worse than a full uptier, because you could not choose every vehicle to play. But still general composition were symmetric between teams.
And that is all I can say, mode got shelved (to the point the last WWM event is closer to the release of the game than today), historical matchmaking got abandoned and every tree gets the same vehicles each update
Late to this party France needs leclercs that don’t immediately get bumped to 12.7, they have 4 all at 12.7 already, they need a re-work maybe with the s1 and s2 dropping to 11.7 - 12.0 seeing as the msc already sits at 11.0, i would say give them back the OFL120G1 as a stock round then the F2 as their top round. The Sxxi and azur can stay where they are then there is a spot for the embt.
