Imo the main issue with maxim (as with other support weapons on wheels) is the "death loop" animation.
I agree with this however one thing that isn't talked about in regards to the Death Loop animation is LMGs or All Range type weapons like the FG-42.
Group of:
Riflemen with LMGs can death loop MG-42/34
Infantry Sections with LMGs can death loop MG-42/34
Penal Spam/For Mother Russia can death loop MG-42/34
Fallschirmjäger can death loop allied MGs
Obersoldaten can death loop allied MGs.
Grenadiers can death loop allied MGs.
So the elephant in the room that no one really talks about in regards to the death loop animation is LMGs or long range rifle type weapons (FG-42/SVT-40) that should have a damage penalty vs HMGs except in green cover and would help with blobbing overall as a whole.
These weapons should hard counter other Infantry but be weaker vs HMGs which would give them a clear role instead of the instant upgrade rape all things that they currently are now.
If these weapons had say a 50% penalty to HMGs across the board (except in green cover) for all factions death loop would be a thing of the past.
