Ok let me reiterate when I mean high damage output. It wipes out squads entirely, the impact it has on the battlefield can be tremendous when the Germans only have a few infantry squads left and a lack of manpower. It has been like this since beta.
Incendiary barrage is a guaranteed squad wipe? You can press retreat and the mortar will always escape unless something else is hitting it. The incendiary round does so little damage because flames relys on crits to kill now. However, I never seen an incendiary round instantly wipe out a squad. It's always just 1 or 2 squad member dies before they walk out of there or just none at all.
I'm not one of the people that say the thing is completely uncounterable but the thing is pretty difficult to kill. After all it's an mobile artillery which would be firing safely behind the front lines. You're talking about rifle nades and other infantry assualt on the mortars, but I could just say the same for the German mortar. The problem still stands, the 120mm mortar is just too good at squad wiping compared to everything else the Germans had, and the Soviets already have enough squad wiping tools anyways.
