US Motor Pool suggestion and building destruction

Hear me out, What if the USA 75mm GMC had the ability to switch between a tank destroyer mode (firing projectiles with less AoE and damage but greater precision) and a light artillery mode?

I think Company of Heroes 3 should focus more on lighter, more compact vehicles, as it’s historically accurate as well. Let medium, Heavy tanks stay it is but they should focus more on lighter vehicles. (Such as adding unique abilities for each light vehicles.)

As for building destruction, any larger caliber weapon should have a significant impact on structures, similar to Battlefield V. If infantry are inside the building, it should cause more damage, with greater collateral effects, like entire walls collapsing. That would be really cool!
