counter play
Counter play of doing suicide all-ins into at gun walls and mines? We already had it with ISU.
Game shouldn't just be "I know how to retreat my infantry so I have 999 infantry squads blobbing around late game".
Yet you propose exactly that with -50% damage from rockets on retreat.
infantry preservation is something you learn after 100 games. It's really not that hard to keep your infantry alive.
BS. Infantry dies to mines on retreat paths, it dies to demos, it dies to light vehicles and overextension, it dies to flanks, grenades and RNG mortar shells, it dies to tanks, it just dies. Everybody loses their squad in a course of games, and vetted and double upgraded squads should be a factor in late game, not something which would be erased in one barrage.
If you don't take the action to destroy the arty countering your giant inf horde/battlegroup cluster fuck of infantry.
You wish calliope was only good against infantry. It good against everything short of tanks and wipes OKW trucks in 2 barrages on med range, exactly what kat where doing when relic decided to overbuff it beyond any considerable reason. And together with werfer it wipes blobs and single squads alike, causing tremendous amounts of bleed by very little effort.
You must make counters work by using them right, which is not the case with werfer and calliope.
