Haven't played it yet, but I will say that this looks downright fishing epic. I'm also most likely in the "I don't find this boring" group, as I don't mind tedious activities.
Although the difficulty needs to be balanced a bit better from what I can tell in the video... that first spell is piss easy, and so is the third, while the second and forth require you to actually pay attention.
EDIT: Actually, that entire battle looks pretty easy for lunatic... but I can't really say that, having not played it and thus have no idea how it handles in the controls department.
