This wouldn't violate current AI systems, considering the existing AI only follow your route or teleport to PSO2 Meseta you if they get stuck. I'm thinking it will be a similar approach to what Dragon's Dogma Online had. The world is huge and open, but everything outside of towns was instanced. The world is huge and open, but everything out of cities was instanced. They watered down the scaling to a formula and transformed a bunch of classes but today that it has gone I constantly want to play it.

I would absolutely love Dragon's Dogma Online-styled experiences in Phantasy Star if because it gives us a reason to learn more about the world (or at least rapid travel to it to jump in and out) and to also have a challenge with all the bosses and enemies.

I'd imagine with how New Genesis would possibly be balanced which hopefully every class is viable like how Dragon's Dogma Online cleaned up the vocations so that they were all complete packages that gamers can enlarge on and flesh out without needing to engage in matters like exactly what Phantasy Star Online 2 now has (specifically Mags deciding which courses you will excel at along with your ability tree also ascertaining what you gain and lose). 

I'd drop the entire ability tree, and the most important class/subclass method to have something like Dragon's Dogma Online failed with all the habit skills, core abilities, and also the augments with the capability to buy meseta pso2 mix-and-match reinforces, which everyone unlocks core skills and contains them collectively, and that players set their playstyle with their spiritual skills.
