It will definitely be the normal MMO system. Combat will be quickslots and one clicks, and leveling will be the usual "get to level 9 or this fucking mission is too hard for you!"
I became really bored with MMO's as you are tied down by your abilities and level.
At least in past Elder Scrolls games, you could go into a dungeon where you know you will get fucked up and at least try and attempt it.
Heh, maybe with a little luck, you could succeed.
