What do you want to see in KH4?
-Personally I want Shotlocks separated from keyblades again(maybe have them change when transformed, but I want to equip shotlocks regardless of keyblade)
-I also want unique movesets for keyblades before transforming I want each one to still feel different.
-I want D-links back whether they replace summons or not, but I'd like Riku and Aqua to get major buffs from their KH3 versions if they become D-links or playable in general cause they could not compete with Kairi and Roxas who were way more fun
-idc if FF comes back so long as we at least get a SE crossover preferably TWEWY cause I want to see Sora remeet Neku
-I want mirage arena back(still giving exp and materials) and every boss refightable either through it or battle portals
-Disney wise I would want at least one fox world tho I don't expect one I'd like to see it Simpson's is definetly the most popular, but I'd like a Futurama one I'd find it interesting for them to meet the Planet Express crew and have Sora compare the different kind of worlds they visit(I actually haven't been watching many Disney movies in the past few years tho I think he could have good chemistry with Moana)
That's all I can think of rn
