If >!Jadzia had been killed!< at the end of Season 5 instead of the end of season 6 I think Ezri would have worked a lot better. Cramming all of that into one season while also trying to wrap up the Dominion War was a mistake, but one they didn’t have a lot of alternatives for if they wanted her to be a full fledged part of the cast.

Of course Rick Berman >!not running Terry Farrel off the show in the first place!< would be the best case scenario but I do like Ezri, just not how much time was devoted to her in the final season.
