The gore attack actually is a bit of a nerf. The 2014 minotaur skeleton charged and gored for 22 points on average (13 (2d8+4) plus 9 (2d8)).
Edited to add: They beefed them up a bit by removing the Strength saving throw to avoid being knocked prone. If you get hit by the 2024 gore, and are Large or smaller, you're prone. Not sure how I feel about that...
Edited to add 2: The charging gore is further nerfed, as the 2024 minotaur skeleton needs to move at least 20 feet to get the charge bonus. The 2014 one only needs 10 feet of movement.
They further nerfed them by removing their greataxe attack. The 2014 minotaur skeleton with a greataxe does 17 (2d12+4) per attack
and does not need to charge beforehand.
