The Sturmpio combat package still costs 70 muni (like that winter coat is sooo important in auto match games, which should be the main focus of balancing).
Needs a price reduction or, as it was suggested before, allow the minesweeper to be acquired too. I know sturmpios having a schreck also means they can vet much faster, but still, that 70 muni is just too high. On top of that it means you need to get a second squad of pios for the sweeper, which is generally unadvised for OKW.
Better Combat Package and flamethrower not lock out sweeper,and maybe after upgrade combat package give Stormpioneer some ability or buff
