I'd absolutely love Dragon's Dogma Online-styled encounters in Phantasy Star if because it gives us a reason to PSO2 Meseta learn more about the world (or at least fast journey to it to jump in and outside ) and to also have a challenge with all the directors and enemies.
I'd imagine with how New Genesis would possibly be balanced which hopefully every course is viable like how Dragon's Dogma Online cleaned up the vocations so they were complete packages that gamers could expand on and flesh out without having to engage in matters like exactly what Phantasy Star Online 2 now has (specifically Mags determining which courses you will excel at along with your ability tree also ascertaining what you gain and lose).
I'd drop the whole ability tree, and the main class/subclass system to have something like Dragon's Dogma Online did with the habit skills, core abilities, and the augments with the capability to mix-and-match augments, which everyone unlocks core abilities and has them together, and that players set their playstyle with their custom skills.
A large part of the preference for me is so that you could surely invest your time and resources into updating and unlocking new abilities and skills and then after you are all done you can return and mix-and-match things to your liking without realizing you would have to fall in cash just like you currently do if you wanted to construct something like an optimal principal course tree and a version for an optimum subclass tree, or invest in a different Mag since you are missing about 6-7percent of your overall harm (and therefore are overlooking 200 points to cheap meseta pso2 equip your weapons/units).
