Ah yes, then ony USF can have an at blob of doom with bazookas on every rifle squad. Better fix everything at once
While I don't disagree with you I feel like the way that the factions are designed that Volk shrek blobs are more of an issue because
1. Allies (USF in particular) have tanks that are more lightly armored and completely shut down by Shrek blob
2. Shreks greatly accelerate Vet 5 on Volks, who have a higher ceiling than Rifles.
3. USF suffers from more MP bleed (Rifles are more expensive to build and reinforce), this punishes a USF player more for recklessly blobbing.
4. Shreks are still better than Zooks (yes, they cost more but realistically a USF player isn't going to build 2 zooks for every 1 shrek)
5. OKW late game (Obers, KT, Etc.) is much more forgiving to snowball into with Shrek Volks than USF mass bazookas into... Pershing?
It all makes the Shrek blob issue a bit more pressing
