30 muni to kill 2 models from gren/pgren/spios squad are totally worth it. Not sure about volks squad.
My problem with generalist mines is that infantry clear them before vehicles, while I would like them to do engine damage, not to just bleed my opponent. In that way I like Teller mines more than 30 muni mines.
But no complaints here.
I like that part of assymmetric balance.
I think there are no reasons to change it.
Ostheer is the only faction suffering from blatant munitions starvation.
No other faction in the game has any problem with munitions whatsoever, so I really don't think this is a concern.
I disagree.
USF and UKF have more mandatory munitions sinks (double equip on all infantry) in comparison to single 60muni LMG-42 for grens.
The only munition sink that is special to Wehrmacht is 60-muni medic bunker. Everything else is equal or less than other factions. Even soviets now have more munition requirements, if they go penal/guards meta: Penal flamers, Guards DP and optional mines and demos here and there.
It is quite hard to compare commander abilities' costs and necessity though.
