So why did they wait until now to address them?
Because they’re not things they were willing to address with errata or additional design, hey we’re just going to have to wait until a major revision. Well, that, and none of them were causing a majority of players to be unsatisfied, they just weren’t hitting ideal targets.
But they are more resistant to them.
There are many EnWorlders, game designers, and content creators who often talk about not rolling during exploration and social encounters and having long grindy dungeon crawls which would benefit short rest classes.
They would not run into these problems.
Sure they would. That style of play is very uneven in terms of encounters per day, difficulty of encounters, etc.
Which makes they overall avoidance of some off these often discussed 5e complaints and criticisms until literally yesterday confusing.
First, this is irrelevant to the criticism I laid out that started our exchange. The fact you find it confusing is not evidence for any given supposition you want to make bold declarative statements about as if explaining facts to someone.
Second, how is it confusing? See above.
They tried to use class and subclass features to make up for pain points in certain classes, and in some cases it mostly worked. In the cases that didn’t, they were not ever going to go beyond that before doing a deep dive survey and creating a major revision to the game.
As for the idea they ignored them until yesterday, that’s simply not true.
Taking warlock again, UA5 addressed the same issues for warlocks. Much more radically.
