4) further questions for the people who think it's balanced right now:
a) what do you do to counter it on a map like Semois or Kharkov which is heavy on buildings? have you had any success on these maps against players who are just as good as you Ostruppen spamming?
b) what is your recommended counter?
c) at the earliest time your recommended counter can hit the field, assuming even map control, how many Ostruppen squads can be on the field?
d) what is the cost of your recommended counter (include the manpower cost of T1 or T2 if you have to build that straight off the bat...) - how many Ostruppen units does it cost?
Semois map is one of the most unbalance map in my eyes as top side fuel point is very easy to defend. Kharkov on the other hand didn't got much play on that map (only 1 game and i wasn't using Ostruppen) so no comment on that
i do had few rounds fight with Ostruppen on Semois, but as usually i won if i spawn top side and lose if i spawn lower side. i am agree that fighting Ostruppen from house to house is pain. from my experiences fighting Ostruppen summer maps i like use FHQ or 120mm commander and anti infantry during winter.
I normally use Maxim (3-4 of them)Spam with 2 flame engineer and 2-3 conscript (build before i saw enemy using Ostruppen) to clear the house advance and back up by AT guns, again i don't need worry about MG42 or mortars when fighting Ostruppen because they don't build those then see how things goes. the Ostruppen player i counter don't feel that good because they don't bring much other infantry out (except officer that really not enough in my eyes) to backup Ostruppen, if they spam trench is actually what i like to see just Molotov and trench is mine
i won't say i am good at Ostruppen spaming. i am still trying to find a way to play it comfortable with Ostruppen. a problem with Ostruppen spaming is to know how much to spam, few games i had over 15 Ostruppen (i think) on the field but it give me the feeling that i am overwhelmingly winning until soviet bring out their 120mm, guards or shocks. even Ostruppen are cheap but i still bleed out MP to hold my army large then got into that part i am low on MP to bring out enough better troops like pgren and tanks with all the fuel and mu. i find hard to bring out panther in late game with this commander and couldn't bring out pgren and p4 fast enough. right now i am usually spam like 10 of them then start having pgrens to hits the field.
i hope this answers the questions
