Hardmode Corruption/Crimson/Hallow spread. If I could remove one thing from Terraria, it would without a doubt be this. Holy
why.
Green Solution replacing Mushroom with Underground Jungle. Again, why.
The Moon Lord drop rates. 11% on everything worthwhile? Make the player have to go through the Lunar Event every time? Sure, why not. (EVERYTHING IS WHY NOT)
1.3 Antlion subspecies. Nuff said.
Seasonal events. Why do I have to wait half a year just to wear a special outfit again?
Mobile controls. It shouldn't be this hard just to freaking jump.
The Angler.
The Angler.
The Golem theme being reused for the Lunatic Cultist and the Desert and Jungle themes being reused underground. I just don't feel like they fit, honestly.
Pirate and Pirate Staff pirates pooping on the floor. I like the reference to Pixel Piracy, but when I'm just playing casually, it makes me feel like I'm watching Smosh. (see also: uncomfortable)
Zero Suit Samus getting buffed for no reas-wait, wrong game.
Expert mode being too hard to play with a fresh character, but too easy to play with an endgame character. A bit of a pet peeve, but it kinda bugs me regardless.
Orange Bloodroot. Where the heck do these spawn again? Dirt ceilings? Yeah, because those are so common underground.
Pyramid. Spawn. Rates.
