So I found something... unusual and different between 1.07 and 1.08 on links upsmash damage.
In 1.07, when hitting a grounded enemy and link is facing him, damage will always be 18% for all three hits (and combo counter breaks). However when hitting the same enemy when facing has his back to him, damage will be mostly 17% with some 18%s here and there, and combo counter works.
In 1.08 this is kinda reversed. When hitting a grounded enemy and link facing him, damage is ALWAYS 17%, and combo counter works. If hitting an enemy with back turned to him, damage will mostly be 18%, with some 17% here and there and combo counter works.
Difference is probably super small but wanted to point it out, guess this is a minuscule buff since damage is now more consistently 18%.
I got pictures only since I thought it was an outright nerf, would need a video to show other differences.
