The 3D, behind-the-back, realtime combat system to copy is not Skyrim, but is instead Kingdom Hearts, and even Final Fantasy realized this, which is why they're doing it for 15. That system is based entirely on the player's skill and reflex, instead of numbers, and their ability to use their skills to close the gap between the enemy's powers and the player's defenses (i.e. Dodge Rolling, Blocking and Flying).
With that said, the system for this game looks closer to that format, abandoning the hit and wait system that was prevalent in Ocarina of Time and Majora's Mask, but I'd like to see more of the different and unique enemy AI in the finished game. We know bosses all have to be distinct, but it's also important for there to be a decent amount of archetypes for common enemies, so they don't all feel copy paste with a different skin.
