I think they were simplifying some game mechanics, which I think it's a good thing.
I could be wrong, tho
You are right, in that they are "simplifying" some things (to use the term easily..."simplify" is subjective and debatable). Whether or not the changes are "good things", then I suppose we'll wait and see.
I personally, don't care. Unless some major setback or apocalypse or something happens, I plan to go hard into GGS. I love GG (tbh, I'm a late fan, didn't get into it til 2017) and the only change so far in GGS that has irked me a bit is the change to airdashing. The rest are all things I don't mind. Even the auto-tech. Regardless, I'll just adapt as necessary.
edit:
on a non-mechanical note, i do not like the new body looks for some characters. But...I'll have to get used to it.
