Arguing for balance changes sort of makes sense BEFORE a change is made, not really thereafter, when its been stamped by Relic. Then its sort of been approved by a higher power, with better resources and understanding, if you know what I mean.
Most balance changes are done when developers see the ruckus the community makes after a change
(Katyusha recent nerf e.g.). So I think that yes, complaining about a recent change in the official and fan forums is useful and can help to revert stupid nerfs/buffs.
The thing is that Soviets were in a terrible state since WFA was released with so few viable strategies, and everyone
(even the very soviet players) complained about the boring metagame the faction had.
Relic's answer has been nerfing conscripts, Guards, T34 and ZiS, and leaving everything else as it was.
I could understand guard's nerf, as button has been always a controversial ability, but Zis, T34 and conscript's nerf are plainly stupid and unnecesary. Nobody in the community asked for such changes. If conscripts are going to be shit, at least let them have a cost proportional to how much they suck. 240 MP for a unit that underperfoms and doesn't scale at all like Grens and Volks is too expensive.
Now soviet faction are even more broken than last month, and no, I don't think the answer to the issue is adapting to it.
The faction is broken as the 80% of their core units and doctrines are plainly useless. And what is worse, is absolutely boring to play with and against them.
Relic should stop their secrecy and tell us in rough lines what future ideas they have for the faction, because pqumsieh's last cast only makes me to lose all hopes in the game.
