The only thing I'm particularly annoyed by is the changes to racial attributes. Some of the other stuff annoys me, but that just completely threw off my plans for the game. I don't plan to play a human, shield dwarf or half-elf until mods come out to revert the changes they have received, despite my original plan being to play a half-drow sorcerer. Of course, Larian is a company known for listening to feedback and providing options, so perhaps they'll add a toggle to switch back to the PHB racials, or at least a toggle for those races heavily affected by the changes.
