Because Vipper's "fix" is abhorrent.
Also because Relic won't allow large changes.
For me that isn't a large change. Changing two existing units with each other isn't large, less change than in actual balance-patch.
And the effect on Ostheer's needed revamp would be also greater.
Edit: The problem of Ostheer's tech-system and units are obviously, working around doesn't fix the problems. And at the moment nearly every unit of Ostheer lacks behind by changes made years ago, but never touched them with the needed consensus.
e.g.
-
- StuG E still is a bad unit, moved from cheap tank-hunter to useless doc vehilce while Ostheer is lacking for a Scot-/leIG18 clone in their non-doc line-up.
- Like StuG E, Brummbär was moved into a role is never should become. It should be a exclusive since release.
that are line-up problems can be fixed by changing the line-up. So the units can offer a real role.
