For me the biggest areas would be to have meaningful choices that cover a reasonable range of choices, and then have real consequences following from those choices; meaningful reactivity from the world to my PC; my PC being central to the story; using the DU concept to provide a range of PC choices (while dropping the "origins" concept); a more balanced distribution of alignment personalities for my companion choices; no railroading; meaningful ways to avoid combat where the outcomes are not inferior to the outcomes from combat; the game being playable with a range of party sizes; and, ideally, a move away from DnD mechanics.
