My group had an absolute blast with Tyranny. And the one-book version fixes a lot of the balance issues from the original two-book release. Just be sure you get buy-in from your players to go into a town that's being attacked by an adult blue dragon at level 1. Beyond that, it should be pretty...
Surely that depends on the campaign? If my DM homebrews an adventure called "The Necromancer's Pits of Deadly Death," then I would expect necrotic damage to come up way more often than radiant.
I feel like your premise here is flawed, because we have no way of knowing what deities do or don't do in people's individual games. Every GM is free to use deities as much as they like or don't like.
Here's the thing, though. Taking LTH is my group signaling how they want to play. They want to be able to have a lot of control over when they can get a long rest. If I mess with that too often, then it just becomes antagonistic DMing--not to mention that at a certain point it may strain...
I rated my campaign(s) at level 2. I regularly DM for two different groups, both of whom take Leomund's tiny hut as soon as they can. I can throw a few obstacles in their way, but messing with long rests gets a lot harder after they have that spell.
Early 5E published stuff often encouraged degrees of success or failure depending on the margin by which the player beats or misses the target number. That seems to have gone by the wayside, probably because players didn't like it.
I realized some time ago that one of my favorite archetypes is the small-sized character who makes giant explosions, either with tech or magic.
In D&D, my go-to small folk are halflings. I tend to like them as savvy city-dwellers rather than bucolic hobbit types.
Knights of the Dinner Table had a storyline recently featuring an oldschool grognard GM who insisted everyone draw numbered chits from a cup as a randomizer instead of rolling dice.
The session ran long, and we only got a few rounds into the combat before we had to pause it because of a combination of people needing to get dinner and me developing a pounding headache. I hope we'll be able to finish sometime in the next couple of weeks.
I created two levels of mistwraiths...
