What isn't acceptable is the way in every apparent respect the gamer isn't given any indication whatsoever that he can't proceed from the Light armor side of the Smithing skill tree to the Heavy armor side. The perks are in a loop and connected, with the highest requirement being Daedric, at the apex of the loop. It, for every intensive purpose, appears to be designed to allow someone to proceed through one skill set (light) to the other (heavy) or vice-versa. Of course, what I found out at level 45 after investing all those perks in one side of the tree and having none to spare, is that you need the entire tree just to get both Glass and Daedric legendary items.
How upsetting to light armor users who (inevitably) want legendary Daedric pieces.
