What is a lost gameplay mechanic you want to return?
I would like rope darts to return. They were only in the Kenway Saga. You get a rope dart as an ability in Valhalla, but it doesn't work the same. Rope darts in the Kenway Saga would allow you to string people up from trees Predator-style. I would also like to see more parkour around trees like we have in the Kenway Saga. If any game were to reintroduce these two mechanics, I think it would work best in Hexe.
How about you?
