Also, if you think 5E has too many options/choices, you can always stick to just the original PHB. (And, did you ever try 3.X?? It has many more options.)
Many players in my group are about your age and go back to AD&D in their play experience. They really lit up when we first tried 5E because they said it felt like 2E (their favorite overall) but with cleaned-up math. By that, they mean things like ascending AC instead of THAC0.
Having looked over the new subclass, it might be because it has been substantially changed. There was (ironically) no actual drinking involved with the Drunken Master subclass, while the Warrior of Intoxication is all about creating and consuming Mystic Brews.
The 2014 version was never married...
Can you expand on this? One comment I hear frequently is that it's too hard to kill high-level PCs, so how do you get character death to work for you in that case?
(Me personally, I almost had a TPK at level 17 in one memorable game. But that was largely due to player miscalculation.)
My opinion is a tad more nuanced than that. I think most of these issues are only problems for certain tables with certain types of players. If you happen to run into those players, you'll see them as problems, and if you don't, you won't. And there's no way to player-proof any RPG, so no matter...
If they ambushed while the party was asleep, they should catch the PCs prone and without armor, however. That's unlikely to be the case while the spell is being cast.
I've had multiple cases where I was running a published adventure that called for an attack during a Long Rest. That obviously gets negated by Tiny Hut.
But the premise is also that the hypothetical new game is "innovative" and strays further from 2014 5E than 2024 5E does. For those who like 2014 5E, it's a confusing premise.
