Tbh, patch 1.1.1 really hasn't affected me much if any. I still play the same way, and still get the same results.
One of my old problems with Palutena was I relied way too much on aerials. And you get seriously punish for mainly using aerials in Smash 4, especially for Palutena's case. It was a problem that stuck with me for awhile.
I tried making some quick fixes by getting faster with Palu, and using Jab more, but that only did but so much on characters like Sheik and Diddy. I came to the conclusion that I needed to improve my ground game.
So I started pivoting. Was surprised just how effective it was. With this, I made use of things like DTilt, UTilt, Grabs, and Jabs. Something that I knew of since launch, but never made use of (I blame Mario for that).
The results, are satisfying. I manage to make Second place in a local Tourney with her alone. And I'm starting to feel more comfortable fighting Sheik and Diddy. Zero, Pikachu, and Luigi are manageable, but I still need work with Rosy. That Luma ruins everything, lol. Even when I use Mario I still have a hard time. But than again, I haven't fought many Rosalinas, so that could be a reason. :/
