I am not sure what your point is.
Iyo is FMR a bad ability?
Iyo the other abilities of the same class are better and yes which ones?
Iyo is Counterattack Tactics as weak commander that need to a buff?
You say its a usefull ability. That is true it affects more then just inf wich is great. Just i am not sure if and how a maxim will supress better with 50% accuracy buff. Sprint is the biggest part of the ability. Thats what gives the edge on a agressive mobile faction. For okw such abilities even sprint only out of combat can devastating because their guys can do their damage at max range. Their combat bonusses being lower during the ability shows that.
But i agree with op that this nerf was the wrong way. Soviets are affected more with this kind of nerf/bringing in line. Them being in large a faction with short to mid range inf.
faction wasent kept in mind here imo. Just ow hey thats different that isent right, while imo soviets play very different more so then any other faction. Nerfing the combat bonusses would have been the better choice.
