I don't know about anyone here but the whole shoot through objects had to be implimented because the sturm's shell would hit tiny things and instantly expload, both rendered it a useless crap because it hit a wagon inches in it's face, and wiping out all your own units doing so, unable to connect to the target points,
Cruzz recently confirmed that it's possible to design a unit that can shoot through objects and cover while being unable to shoot through shot blockers such as houses. The sturmtiger obviously needs to still be able to shoot through objects so it can hit its target but the ability to shoot through houses and trees is too much and must go.
If you think loosing full rifle squads is bad wait until you start loosing full 5-man tommy squads to it.
