I don't care about OKW/Ostheer heavies, I enjoy fighting them with Shermans/Jacksons/SU-85's and it feels fine, in 2v2 I have alot of fun using dedicated TD's to fight KT/Tiger/panther etc. The issue is when the vet5 volks blob with the most powerful heat seaking missile launcher in the game comes along and wipes mediums in one volley, honestly ruins games completely - this has become the meta.
For example, non-doctrine US Main deterrent to Heavy armour is a Jackson and SU is SU-85 which does no damage to infantry.. if I invest popcap/resources into Jacksons, I lose a significant amount of my anti infantry power, and I then don't have the capabilities to stop the 30 popcap 7 squad volks horde from just running through everything killing at will.
If a smaller, more fragile unit (Say sturmpio's) had the Shreck, it would be far more balanced. Ostheer have a similar unit (Panzergrens) which you have to decide whether you want a dedicated AT unit or AI unit.. not both. This change would obviously mean the Raketenwerfer 43 could receive large buffs too.
Well, if Volksgrenadiers lose their Combat Package upgrade (which I highly doubt because it is arguably a game-changing suggestion), then I hope you know Relic would implement a different upgrade for them (StG 44 package, for anti-infantry potential), indefinitely. Provided this tweak would synergize well (I wouldn’t know until it actually happened), I wouldn’t be totally against it, HOWEVER, as the Volksgrenadiers stand right now, they are pretty lackluster until they receive their Shrek upgrade, which emphasizes the whole “late-game supremacy” concept that Relic seems to be pushing for when you play as Axis. I feel the real problem here is the ability to blob infantry (USF + OKW are the primary factions in which most players utilize the whole “massed-blob” strat.), which I personally believe is a whole different debate to be had. That’s just my impressions, though.
