You make the problem worse by decreasing infantry lethality. Remember infantry damage was much lower at the beginning of coh2 and cover didn't matter at all. Every squad could just move up to a enemy in green cover with minimal damage and throw their grenades and grenades decided almost every infantry fight, not cover.
Just make machineguns better at killing and bonus vs blobs and decrease their crew to 3 like vcoh because it works and prevents machinegun spam.
