Re-used models.
Spell-casting animations, fighting stance, and bow stance look the same as oblivion

Removed class system
Level-scaling is back
Fast-travel is back
Dragons a common enemy that drop abilities like bullet-time mode and summon dragon.

Sure, individually they don't seem like a big deal...
But together they paint a picture like it's going to be another game in the casual direction.
