It somehow worked in CoH1 to nerf pio spam, it could work for every type of infantry in CoH2 also, my idea is simple, nerf starts affecting squad when there's at least 2 other infantry units (type doesnt matter), in X radius from it, each other infantry unit increases stacking and increases chance to hit this squad by for example 5%, up to 5 stacks, so in very blobby way, one squad could get up to 25% received accuracy penalty (that's 7 squads).
I think this could be great option when current volks blob, PTRS, Zook spam meta is almost in every game
What radius?
If I put 3 squads in cover in the radius does it work?
If I put a pioneer (for the vision) + MG42 (for the suppression) + Volks (for the support) in the radius, they all will receive the penalty? It is going to be 10 times easier to take them down with a good flank
If I have to push to pass a bridge or a narrow path, Penalty?
If I have been pushed into my base - penalty vs that m20/half-track/luch already raping me?
3-4-5-6-7 squads in a blobs is usually enough spread, except when the blob pass through a narrow path, to make your radius large to be effective. And it will affect anything else that is not necessarily a blob.
And last, what about tactical blob? When you need to push hard a point with all your squad to break a defensive line?
It works with piospam in coh1 because its only affects piospammers...
