"Veiled Argunite" wasting 50 days on quest rewards

Hi there,

anyone has a solution to the problem that I have not yet found?

My Veiled Argunite is capped after only a few days of Argus farming and I still need half of the assault point bosses so I take the daily quests from Illidan and Turalyon, but half of this isjust wasted as the vendor that normally sells stuff/transmog on the Blingdikar has nothing on offer so there is NO WAY I see to get rid of/ use the Argunite for anything useful … Why even give us that as quest rewards when we can only hold 2k of it and Timerunning is still 50 days? (No I will not stop timerunning this char early….)

Any ideas?
