I’ve been trying to get hold of the Notorious Gladiator’s Warglaive appearance, and I don’t seem to be able to find a vendor that sells this appearance.
Is my only option for getting hold of this one to save up the 80 Marks of Honor to buy the arsenal from the vendor in the Mugambala?
Yep. Blizzard took easy road and just smashed all weapon in that arsenal. All other previous expansions pvp weapon are on arsenal or you can choose what weapon you want to buy.
