There is a daily in Zul'Drak that all you have to do is talk to the guy and its turned in. Heres my guide:
Step 1: Go to the argent Stand
Step 2: Go to Commander Kunz
Step 3: Right click him to open up his quest menu.
Now click "Congratulations!"
Step 4: This should show up
The bag he has just contains grays and sometimes greens.
Step 5: Collect reward. You can increase your reward by being level 80 and getting exalted.
Please Note: This quest also gives EXP.
This is a Daily so you can come back Everyday!
Any questions or need help leave a message ill try responding A.S.A.P.
