I think using bows is pretty much the same, but the aiming makes less sense. Took time to get used to it because of bad aiming physics with the bow. You can pretty much hit any target by aiming right at it. Don't mind the change overall, but its harder to shoot over things than in Oblivion.
The game is a big improvement though, but I still think lvling is still a problem. Now that enemies scale with you per level, there is a limit to how strong you can get because there are no stats. So if you level too high enemies overpower you because they don't stop increasing their defense and attack damage while you do.
Fun to play, but it doesn't feel as fun to replay as Oblivion did.
