A step backwards doesn't literally mean backwards in time. Otherwise, complete removal of the level-scaling system used in Oblivion would be "A step backwards."
The problem with the Oblivion system is there was no consequence for weapon/spell choices. A battle mage could fight as well as a warrior, and cast spells like a mage. The jack of all trades should be flexible, but not as powerful (or moreso) than a person who specializes in that field. You can no longer run into any situation with the same load-out. There should be a lot more strategy before a fight this time around, as well as changing tactics during a fight.
