Not to mention, jumping when wearing full armour would be a little difficult, and jumping while running/attacking even more so. Sure, it's a game, but I just don't see why you would need to do it anyway.
how does it matter if its realistic or not? its just a basic feeling of freedom, all previous tes games ahve had it (atleast the ones I've tried), and there is no reason to restrict us like that. and besides that, that still doesn't excuse the lack of sprint jump.. the game feels like it only allows you to do one thing at once
For an examples of the air attack thing. I was fighting on some stairs, and because I was running towards an enemy downwards, I was in the air for a little bit every so often, which prevented me from attack. other than that, its one of those things that are just fun to do.
