Losing a position (by a wipe or by a retreat) because of an OP ability like the ZiS or SU76 barrage is almost the same. You lose the position!!!
Almost the same huh and a op ability huh?
When you retreat you loose the position to. But if lucky you dont even need to reinforce only heal and its back on the field.
When wiped you loose a team weapon. meaning you need to spend a lot more mp to replace, the enemy might take it, or you need to make a big effort to recrew it.
So how that is almost the same is just wrong.
And the barrage being an op ability is not true imo.
But aparantly soviets are not allowed to force the enemy off or to make them move their team weapons. Not even a small chance to wipe if rng is willing.
