The only reason I am is because another user here, Hussar, very kindly offered to let me join his group, and he has been nothing but a great GM, so I have no complaints.
And yes, my experience with 5e has been miserable (outside of Hussar's campaigns; again I want to stress how distinctly different he has been from all prior 5e GMs). A very large portion of it has come from either GMs being cavalier about the rules, GMs acting with impunity when they should have been more circumspect, or player characters being extremely fragile and ineffectual at low levels. And "low levels" (e.g. 1-3), prior to Hussar's games, were the only levels I ever got to experience.
The designers supposedly designed the game such that people were supposed to skip to level 3 and ignore levels 1 and 2 because they're so fast and don't add much gameplay value outside of new players or people who really really want that gritty feel. My experience has been that very nearly 100% of GMs demand that play start at 1st level merely because it is "first", because you start with the "first" thing, that's what being "first" means, regardless of the consequences that entails.
I cannot say if it is typical or not. I have no good evidence to say that anything else is typical. I have been told by several that it is atypical, but that's really all I have, being told it.
And yes, this is a big part of why I am rather skeptical about some of the alleged value that comes from various elements of 5e's design. I was already skeptical and a bit of a sourpuss beforehand, having felt burned and mocked by the "D&D Next" playtest, since I really loved 4e. The few times I have in fact given 5e a try, it has...not gone well, despite my efforts to the contrary. (I did seek out 4e games first, to be clear, and then non-D&D games that were similar to 4e such as 13A, and then games that weren't even similar to 4e but were still non-D&D, and then even tried giving Pathfinder 1e--2e wasn't quite out yet--a space because at least I can kinda enjoy its gonzo rules. Then I finally said, "Okay, I guess the only way I'm getting to game at all is to play 5e", and thus genuinely tried to give it a shot.)
