I always think it should more easy to use,just use 100 ammo switch 200MP like COH1,or use ammo to call-in Ostroppon or like OKW old firestorm commander when lost soldier return 20 MP
These modes are something I specifically want to avoid. I'd like for them to be slightly engaging and thematic. Flat manpower back is uninspiring and kinda broken (20mp back on cons that cost 18/man? Or grens reinforcement cost 2/3 rebate?)
IMO you shouldn't WANT to take loses, but the abilities should thematically represent how the factions managed with these.
Reserve infantry gives lesser infantry but with decent utility. No match for the Germans they are replacing but more plentiful and expendable--something ost desperately lacks late game or in messy team games. It's a niche but one that shouldn't be abandoned imo.
For the soviet, getting more con squads isn't really an issue at any point, sure the MU-MP conversion is a thing but really if you NEED another conscript odds are you'll just buy one. Furthermore the new 7 man feature makes needing to replace cons much less of a thing than in the past (where funny enough they were so trash you wouldn't want them anyways)
I feel for the soviet QUICKLY recouping costs to keep the line or keep up pressure us what they need, extra mp could work but it's so damn boring and can be stuck anywhere and any faction with no thought at all.
