Ofcourse you love every change thats not good for axis.
Why should'nt he? Axis are in a really good spot for now, always over 50% playing, according to the counter ingame. Pgrens changes, 250 and 251 HT, vet3 gren buff and massive OKW overhaul have made already well-made army into hellish spawn of OPness. I do like play with germans, I am even sort of werhaboo myself, but I'd like me some skills.
As for topic, changes to howitzers seems good enough for me. Pre-patch both ML-20 and LeFH were able to lay continuous area-denial fire or non-stop bombardment on heavvy-traffic area, making easy kills and frustrating enemy. Also, mobile arty spam was a thing.
Now it is more like an offmap arty strike - short, effective, but with big cooldown. However, it almosti killed (IMO) any sort of mobile arty unit, so my guess is to revert chandges for them and do something else to them, like increased scatter or messing with their vet1 abilities.
