You are DELUSIONAL if you think the mortars are balanced. Ive fired hundreds of rounds directly onto packed points. Ive never, not even once, gotten a direct kill. I get a hit for 10-20 damage for every 20-30 rounds fired. Meanwhile Im spotted on the map for everyone to see.
Mortars are one of the most casualtie creating weapon systems available at the squad level. Now Im not saying they should be as good as they are IRL. But there are a million ways to balance these mortar rounds so they are effective without being over powered.
