Discouraging map movement is like the job of Ostheer
you're confusing goals and means. Discouraging map movement is the
goal of the ostheer, because it forces their enemies into the superior wehr support weapon.
giving the wehr one of the fastest tank in the game break the dynamic. (for medium tank at least)
But by design they will never be probable woth axis snares. Its bullshit soons volks got snares falls fusilers should be gone. Also take into account originally allies were designed around the mediums speed and manueverability also historicly accurate. I emplore you to play brits sometime i doubt you would be able to handle with no snares and purely out foxing your opponet. Try fighting a luchs with a the kangaroo wagon when you can be snared at anytime but your oppenent knows you cant snare.
I think you're too obsessed with getting pass the infantry instead of killing them.
the grenadiers and volks are themselves valid targets, killing them will drain manpower just as well.
Mediums in general possess anti-infantry power. If infantry are in the way, kill them, and retreat if enemy reinforcement shows up.
On a larger map the medium tank is more likely to finish repair before the Infantry have a chance to reinforce and walk back up. The forward retreat points are themselves juicy target for artillery. With every infantry that's gone it's more holes for the medium tank to slip through. If the enemy fall back to tighten their front, you push forward back and can get better map control.
Medium tanks are suppose to be flexible. If a heavier unit have an exposed flank you flank. If infantry is in the way you kill them. If you really want to take on a heavy tank from the front, you get tank destroyer to support you. Their long range bypass the damage of snare.
Yes, this takes multiple attempts instead of one big climatic battle, but being able to last through those attempts is what will make medium useful.
