This goes for stock vanilla+ too, the 30mm cannons featured in the boat expansion (i forgor the name) seems to be able to melt any air vehicle in a fraction of a second, yet the identical one on the attack planes seems to take ages to kill even bare infantry, and using it to kill air vehicles is just not viable since you spend half of the match chasing people around and just overheating your gun over and over again until they even reach half health.

Same goes for the 20mm, its literally useless and does ZERO damage to anything.

Also, most armored vehicles seem unfazed by bombs and rockets, since they have such a low blast radius and damage compared to the size of the ordinance itself and the produced smoke cloud, and the same for cannons again, giant explosion, very low damage and AOE.

So yeah, TLDR; weapons like bombs, rockets, and cannons need a major buff in damaged and blast radius, since they are basically useless (except for bombs, but they still arent that effective due to the tiny radius compared to only having a few).
