Agree on battles dragging on for too long. It becomes especially boring when all you can do is one attack and then wait, wait, wait. I often found myself alt+tab to read internet while enemies do their turns.
I guaranty it will exhausted a lot of players in long run, in same way as it did with DOS 2, when only few reach the end titles of the game, while most become bored and leave, in hopes to come back some day and finish, which they never do. And all thanks to long, dragging battles.
