Are you planning to fix the UKF "Assault" too ?
I mean pls do it.
Do you mean Assault Operation? That one is not as strong as VA or FMR... For 100mun only your Tommies are affected, Commandos in the same doctrine are left out (would be way better for them).
FMR basically let your shocks sprint into range, stop and shot, because they can't shoot while sprinting. Accordingly Penals can get closer to get a satchel charge off. Thus both squads will leave less men at their assault and more probabaqly do damage or force off enemy troops. Look at the CP requirements of the different abilities. FMR comes at 6 CPs and is meant to help these troops to get close when there is a lot of AI on the field that makes their live pretty hard. Imagine it would be there when you get your first shocks already... Oh man, that would be a whole different thing. If you want to nerf FMR I would make a ranged ability out of it instead of beeing global (like cover to cover). KW-1 buff recently made this doctrine somehow playable, nerfing FMR to hard will change that. While not beeing an aggressive early game doctrine it is not a good lategame doctrine either because it is missing a strong lategame tank or offmap. So what is its role? Its only real doctrinal powerspike is when you get your first KW-1 in addition to FMR, nerf one and its gone.
I always thought VA and cover to cover are the best abilities of this type. They come in somehow strong commanders while not beeing too expensive for their effect (affecting different types of infantry, especially units like rangers or falls).
