I'd like to see them continue with some fixes for meshing and other issues. Maybe put out a plan for new TLC and/or new map DLC and then a fresh wipe in a massive update, similar to what we saw at the end of legacy. People don't like to think about losing their stuff, but officials are boring currently. Fresh new Officials would bring a lot of people back, including myself.
I agree that they do need to be approached differently, as they've basically different games. Some aspects of the flier nerf could have stayed for PvE tbh. But the mana nerf I don't agree with. There's no reason you need the fastest dino in the game to be DPS haha.
