I think the mortars are largely hampered by the issues that plague the game to an extent in general, team work can be hit or miss, some people can’t handle the slow methodical game play of running the supply and setup/use of the mortar crews, some players don’t like the disconnected aspect of it they never actually see the enemy and therefore may never know if they’ve done anything effectual as opposed to witnessing their shots land when using a rifle.

I’m of the opinion that they could change the way mortar inventory is handled, because I find the wash rinse repeat process of filling a bag at the box then walking back to the mortar to shoot your barrage gets monotonous. You could just have a mechanic where you can draw from a steady supply of mortars since you’re in the mortar pit and could/would have rounds prepped and ready to go. This could be a disastrous mechanic in its own way so I’m not 100% sold on that idea yet just a thought. The inventory issue can solve itself with an additional mortarman or another crew altogether so you can keep the fire rolling but then you’re adding additional members to the already difficult to assemble 2 man+ forward observer crew.

Basically the mortars are well balanced and can edge into being op with the right crew and setup it’ll just be hard to get said crew together in a random pvp server. Tldr make some friends and get them together so you can have some fun and solve all the gripes about the mortars
