What things would you like to see fixed in 5e?

It's not the inter-DM variability per se that's the problem; that's just a symptom of a rules gap.

Are rules gaps a problem per se? Not necessarily. But after you hit enough rules gaps, and patch them yourself, you start to wonder if you're actually using the right system for the kind of game you're trying to play.

That assumes that there's a problem involved in the first place. For me, that "rules gap" is a feature, not a bug. I WANT different tables to come to different conclusions about a lot of things. I want the same table to come to different conclusions for different circumstances. There is no single "correct" answer. The beauty of the "inter-DM variability" issue is that it allows different things to be different without having to modify the system itself. Contra Pex, we're not "relearning the game", because the game explicitly allows certain things to vary. So variance is the game--thinking that it's fixed is using it wrong.
