Crusader AA buff?

as the title says. this vehicle is acquired later then and does less damage  too a near-identical vehicle (in terms of niche/role fullfilled), the luchs. for being a tier higher, it still gets 1 shot by 75mm guns, and in terms of damage output its woefully inadequate compared too the luchs. luchs typically downs a model in a squad once every 2 or 3 seconds, the crusader, despite having double the auto cannons, takes more like 6 secons too down a model. and god forbid you compare it too the flak 20mm, which can wipe whole squads in seconds. i just think it should deal the same damage per shot as the 20mm of the luchs, with the same AOE, and far superior fire rate.
