Redundancy, thats why it was cut from magic. Oblivion had massive amounts of redundancy, with spells and skills overlapping. Beth cut out the redundancy and focused instead on core skills.
I don't understand. So they scrap night eye and instead force you to either choose the khajiit or turn up the brightness? I found myself using it all the time in OB and was irritated when I found out it was gone. Same with feather, my favorite spell...

Also, the open spells were awesome, iknow you'll say it was like a WIN button, but it was a great alternative from lock picking.
And that was a cool part of conjuration, to conjure up armor. Imagine how cool it'd be to conjure the faint blue armor in the heat of battle. I am just really irritated from some of these things.
Honestly, I see where you are coming from, I really do, imjust want you to see where some of us are comin from.
