Nop cuz we all know what does mean super HMG = spam and kill any infantry play.
Do you expect an Atgun to stop a swarm of 3-4 t34, pz4 or shermans? nop. Same applies here. You cannot expect a single unit/260mp stopping a multitude of units costing 270mp+120/140amo each.
Tanks and AT guns are totally different. Suppression does not play a factor in the equation.
You sure as shit should expect a hard counter to stop it's intended target. By stop, I mean suppress, reduce the infantry DPS, and force a retreat. MG=scissors, infantry=paper.
IMHO, The current issue is:
That on some units, when suppressed, the DPS isn't reduced enough.
When multiple targets enter an MG's arc there isn't a multiplier that increases the rate of suppression.
