If anything I think Shwere should have less wipe potential, with more suppression and perhaps a bit more penetration. If you haven't lost a squad or two due to not knowing that there is a Panzer HQ deployed, then you haven't played as Allies xD Otherwise the building should not be changed. But maybe it is just me being used to Shwere being Shwere
Had a 6-man Penal doing the throwing animation when schwer came online. They clumped up to give the thrower some moral support; long story short they got wiped in two thumps. Much sadge.
