As much as I think essentials should have been part of the initial release, the approach of 4e was off-putting when it came to certain aspects of D&D that I enjoyed most.I think 4e Essentials as a standalone edition would have sold better than 5e in 2014 as it was stripped down but focused on archetypes, have a lot more ease introducing modern fantasy character types that work, and would have a DMG that was 10 times better.
4e was the only edition where the barbarian, monk, ranger, sorcerer, and warlock worked and we're good. Imagine if you simplified that without 4e's drama. Money printer.
There's no such thing as a perfect game, I just wouldn't want to play 4E again. [Deleted all the reasons I don't think 4e would have ever been as big as 5. No point. ]
As far as the rest, plenty of people I play with have a lot of fun with the classes you list.
You can't please everyone, but it's not like 5E is some flash in the pan. You don’t get double digit growth for nearly a decade with a bad product.
