I’m just joking i honestly haven’t played a first persona game with good melee combat, or melee combat at all outside of dishonored and mirrors edge.
While dishonored has better combat than skyrim, I'd argue that the dishonored combat isn't even that great compared to the 2 we just mentioned because of the problem we just talked about. There's not as much DEPTH to the actual melee because people want to feel powerful. There's not much to dishonored's melee other than attack, strong attack, block and counter.
What made it fun is having a ton of abilities to go with the combat. So since IJ wont have the magical abilities as a crutch to make the combat fun, its gonna be tough to make it fun if they go that route IMO.
