Of course, that means there's no real downside of using heavy armour. It just feels very un-magelike to waltz around in plate though.
I′m curious who first stated that magic-users in the fantasy-genre can′t wear plate armor and stuff; especially in Elder Scrolls, where Mages using Armor was one of the most exciting and "fresh" things in the series, back in the good old Morrowind days.
This is such a one-dimensional way of thinking, it really starts to ...well. It′s becoming annoying. No offense intended, however.
