Dragonbone heavy armor....It is the #1 MOST useless armor in the game. It's higher tiered in the smithing tree, yet it offers less protection than Daedric armor? I understand dragonscale light armor is pretty good, but why would I go from Daedric to Dragonbone? Makes NO sense whatsoever...
And it's fugly.

Dragonbone/scales are easier to find then Ebony ore AND Daedra Hearts
Dragon plate is lighter for those without heavy armor perks - the armor segment alone weighs 10 pounds less than that of the Daedric.
Furthermore, though Daedric has the higher base armour, Dragon plate has a slightly higher value once both armours are upgraded to legendary. The Daedric gauntlets and boots still out to their Dragon counterparts, the extra armour rating provided by the armour segment, shield, and helmet give the Dragon armour a slight edge over Daedric armour.
