And this is advice that people don't use (as I commented about)
A lot of people don't know the difference between asking for solutions and just complaining.
it makes for a terrible game at low levels too
I think that this isn't really an issue with the adventuring day at that point, but more a more fundamental problem that fixing one aspect of the game reveals in a clearer light.
Low levels in 5e are poorly designed, intentionally, and the game even tells you to skip them if you're not running a game for all newbies.
And ultimately it has to be said that no matter what design or advice issues there are, be it the lack thereof or poor quality, this isn't an excuse to run a poor game that doesn't work.
You have to interpret the rules in a way that makes a workable game or you should probably just play something else if thats too much work. 5e is a known quantity at this point in its life; theres no excuse to act like theres nothing to play if you're not willing to deal with what 5e requires of its DMs to work.
Obviously OneDND should try to fix that issue, but insofar as 5e is concerned, people tend to act like they never bothered to look into the game before jumping in and then, shocker, it bites them in the butt.
Its good game design to not have to require research on the players part to just jump in, but that doesn't simultaneously mean a game isn't fun or can't be if one makes that effort.
That reminds me of Morrowind back in the day. You could have done fine if you actually read the manual, but most didn't and so they died to crabs and rats trying to fruitlessly stab them with a dagger when they specd into Maces. Game was still hella fun once you knew what you were doing.
