Mediocre AI and AT? They have the highest mid range dps out of all infantry squads in the game except falls, and with double schreck they are the best infantry based AT. Saying that they are "mediocre" is just delusional. They perform exatcly like they should for their price.
When u say highest mid range dps do u take into account upgraded allied infantry or just base versions because with 1919 or bars i don't think so.
Double shreck is brutally costly and often 1 shootted fragile 4 man squad.Very few people use them in this way except s quad as stopgap or cover for pak.
No one is saying their price can't be increased if buffed,But lategame against rifleblob with lmg or brit blob they can't do anything with vaunted dps.1 member loss=25% dps gone.Its just too weak in survivability terms.Lategame pzgrens can't do much vs allied vet infantry with lmgs.
