Hanz is so big brain we cant understand him sometimes.
I kinda agree with Hanz's point of constantly trying to buff sub-units all the time.
21stGM has 2 units in it, SO and KU. They dont have every single branch in both units because the units are meant to fill different roles. I think it is an entirely different discussion on how to fix this balance better (imo, get rid of SO SUP, add SUP to KU and remove WS but that's not relevant). KU is meant to be (as I see it) as fast paced, kind of "guard breaker" unit in support of GM, and SO is meant for infiltration. I believe that swapping the Z6 for a more mobile weapon (like the 15x) would be beneficial for the job. However, I believe the core issue with feeling that KU (and in some areas SO) is lacking is the lack of understanding as to how the 21st is supposed to be balanced between sub units.
