Well this is quite simple, basically these commands will exchange lots of high emblems to lower emblems at once, so ya don't need to click and confirm every single one. Think its pain to xchange hundreds of emblems to lower ones.
This can possibly be done with some addon, but if you want to do it fast then check these out.
The guys are at Dalaran, Horde Sunreaver's Sanctuary.
So how it works:
1. Open the NPC window
2. Write the command for corresponding vendor
Change the X to the amount of Emblems you want to trade. Don't change the number, its the Emblem position.
Triumph to Conquest: (Magistrix Vesara)
/script BuyMerchantItem(53,X)
Conquest to Valor: (Magister Sarien)
/script BuyMerchantItem(49,X)
Valor to Heroism: (Magister Brasael)
/script BuyMerchantItem(44,X)
I didn't add the Frost to Triumph because you don't really wanna trade them yet. Similar commands apply to Ally side, you just have to count the vendor items and change the number in command to the emblem position.
