If you actually removed the "shooting through buildings" from the Jagdtiger...what would distinguish it from the Elefant??
Although im for a Jagdtiger and ISU nerf.
Stats-wise the Jagdtiger is superior.
1280 vs 1040 hp
525 vs 400 armor
550.0/525.0/500.0 vs 440.0/400.0/360.0 penetration
Also I think it has 10(?) more range than the elephant.
More expensive of course, but you get a stronger vehicle.
