These are not the final changes. Maybe those changes will be introduced in further patch versions.
I was more wondering why the small edits to non-overperforming units made it into the initial scope. Fixing the OKW tech fork, reworking indirect fire and tuning down some overperforming units and abilities are all high priority changes I understand and can get behind.
There are a lot of little edits to units that don't seem to be high priority, however. I don't personally understand why the little nerfs to non-overperforming units (the Brummbar, Katyusha and SU-85 for example) made it into the first set of patch notes when what I'd assume to be higher priority changes, such as fixing the USF tech fork, didn't.
I'm not saying there isn't a good reason for it, I just don't understand what it is.
