As far as i can see, everything is scaling rather appropriate.
I could kill most Vets within 2-5 minutes by myself, did the UQ in 11 mins solo and cocoons within time. At the very least, if you don't want to you don't have to play with anyone, and for the most part it will be easier.
In terms of combat. It's fine. I never thought PSO2 needed a huge upgrade or engine switch all the problems i had with it was with the lack of commitment to making interesting quests / scenarios. Considering this probably wont change and everything will mostly be gravitating towards zerg type fights, I will probably be sad that PSO2 had to die for this.
But it depends of course where they go from here, as i see it, no matter if it is PSO2 or NGS, it will still have the same developer who loves to cut corners and toss us into guruguru quests with no real thought put into it. I'd be more hyped if the game was picked up by a different developer, rather than recieving a new game from the same developers.
I'll keep my expectations moderate.
