I've now run two campaigns to 20th level, (plus a few DDAL Tier 4 scenarios) and I'm pretty happy with 5E.It would be interesting to see how many of those of us who are frustrated with 5e and would prefer a greater revision of the game have played/focused more on the higher tier levels which require more DM tinkering of the game for it to work well.
My main problem with the last level 20 campaign - Sharpshooter - has been nerfed, so I'm a lot happier.
Cheers,
Merric
