The walking stuka's and PW's lethality is justified by the soveits having 6 man squads. It is broken against USF though. Katyusha has superfast rockets which almost always grant at least one wiped squad. Callie and LM are the only balanced units IMO.
TLDR, all artillery need to be redesigned. They might be somewhat fine in 1v1, but that mode is irrelevant and not played much (reality check).
Exactly, this game is only alive because 4vs4 mode i hope coh3 will be more focused around 4vs4 games. 1vs1 are only for streams lol
