If the mines could be easily coded where they would always, only take out 50-60% of the squad's total health with 1-2 model losses every time, sure, but nothing in the Attribute Editor makes it that easy. It would need to be new code.
plz dont fix smth that isnt broken. Mines are 100% balanced. Munitiouns cost more than MP and placing a mine is a risk itself bcs of mortars and vehicles. If 30 muni mine just kills 1-2 models it isnt enough to pay for itself.
It must reliably kill half of the full squad with some chance to wipe as for instance heavy tanks shots also wipe.
50 muni teller oneshots a light vehicle that is more expensive than all infantry squads. 1-2models is only ok for trip-wires.
