It improved a bit, and then the studio began working on an overhaul internally to provide what the game should have been, sort of No Man's Sky style... but they were shutdown by Bioware.
There's a lot of reasons it ended up the way it did, development hell and poor management mostly. Hell, the flight mechanic, which had been added and removed several times in development, was core to the released game, and easily the best part, apparently wasn't even decided to be a necessary feature until Patrick Soderlund, former head of EA studios, was very disappointed in a demo BioWare had shown in early 2017 that the team decided to add flying back in.
One of the core pillars of the game was essentially added just to impress an executive and keep the development going versus being canceled. Flight like in the game requires the entire map and structure of the game world to be different. If you can fly,. you now need to take advantage of the vertical space, something that simply doesn't even get considered in most games. A mountain you can climb is not the same as needing to fill in an entire mountain range and canyon region with content.
No, that was just development on the promised No Man's Sky-style recovery they were working on.
