This is actually what kept me from running 5E for a very long time. In 4E, I enjoyed DMing. No edition of D&D has provided such good, reliable tools, guidelines and information for the DM. Possibly no RPG ever has, actually. 5E, which I like a lot, certainly does not. The encounter-building and monster-design particularly are far less brilliant than they were in 4E (though still streets ahead of 3.XE). The only other player who liked DMing was away for most of 4E, so I had a great time being the DM all the time.
With 5E, I've had an okay time DMing, but it's not been as fun/engaging as 4E (where it was literally fun to prepare adventures). Fortunately, with me less keen to DM, one of the other players stepped up, and then the other long-time DM (my brother) came back, and also one of my friends wanted to run a separate campaign for some of us. So now I continue the old campaign occasionally, but am having huge fun playing in other campaigns. These things work out I guess.
