The day after I dinged 60 I got the item Deathbone Legguards as you can see in the picture below.

Today I got a new tanking item from UBRS called Warmaster Legguards which you can see from the picture below
Warmaster Legguards
When equipping the items I noticed that I got LESS HP from using Deathbone Legguards (20 Stamina) and MORE HP from using Warmaster Legguards (15 Stamina). I fund this a bit weird and in some way funny, so I linked the two items to a friend of mine to check if I got something wrong. As you can see in the picture below I've linked both the items in the chat (which displays as blue color) but when he opens the item it appear as green and does not have Stamina stat at all on it. So in conclusion this item is bugged. On WoW websites the item is displayed as a blue item with 20 stamina and defense + which must then be the correct stats this item should have.
