Hello! If you are like me and have all the WG items i have the right thing for you to do with them. Not many pvp items is disenchantable but the items from wintergrasp is so what you do is buy the belt that only costs 15 marks.
Link to the belt:
Titan-forged Belt of Triumph - Item - World of Warcraft
It disenchants into abyss crystal:
Abyss Crystal - Item - World of Warcraft
I took the leather belt becouse im a rogue but if you are warrior you buy the plate belt ofc.
So if you are like me and have over 100 wintergrasp marks and you dont know wtf to do with them then just buy this item and dissenchant it.
What to do:
1. Get alot of WG marks
2. Buy your class belt from the marks.
3. Disenchant them into Abyss Crystal - Item - World of Warcraft
4. Go to AH and sell the Abyss Crystal - Item - World of Warcraft
