Hello!
Love the changes so far, but there is one negative change that greatly stands out to me, and that's in relation to the new Graveyard biome.
The new biome is a cool addition, but it simply spawns way too easily, dominating any other nearby biome. In particular, the biome is created way too quickly from tombstones spawned by player death.
I play on a server with 5-6 friends or so. If a few of us die in one spot, the screen already starts to turn grey. If we have a teamwipe on a boss, suddenly there's a graveyard biome right in the middle of wherever we were, spawning new enemies and making it harder to see things. If there's a tough fight right around town - most notably when we had an early Blood Moon - then we quickly have the darkened screen and mist obscuring things.
Previously, player tombstones were a neat memoir of battles past. Now they are an annoyance that we have to clean up after we die - which is extra annoying early on when breaking tombstones can cause a tough fight with a ghost.
I would ask that the required tombstone count for a full graveyard biome be increased, or a change wherein the biome spawns from tombstones that are placed by hand and not from ones that drop from deaths.
EDIT: Just to be clear, I perceive it as an issue of annoyance, not difficulty. I'm playing on Master Mode and I expect to get wrecked often. But graveyards are, more than anything else, annoying; and annoyance should spur change moreso than difficulty should.
