I think I have to agree with the others... if you wanna get the badge, grinding
regular mobs around ogri'la is like grinding for a world drop.
Personally, I'd go do sethekk halls/steamvaults until dinging 70, then do all the
quests in nagrand, blade's edge, shadowmoon and netherstorm, that is a _lot_ of
cash when you do them at 70, and many are done quite fast.
Start doing the orgi'la dailies, and once you're honored study the Legion Ring
event (Shartuul). Read tactics and watch videos and other people do it.
Best way to start off is to get a Crystalforged Darkrune, a Darkrune, 5 Darkrune
Fragments and a Kronk's Grab bag, you learn it faster by doing more tries in a row
than once a week.
Here is a good link that helped me a lot:
http://avatarsofdiscord.org/forum/showthread.php?t=4046 I also have found it immensely helpful to macro a few of the abilityes so that I
can hotkey them (I believe it was '/click PetAttackButton1' if I am not
mistaken, change the number for corresponding ability), and also since I use
Bartender3 addon, scale up the pet bar so it is large and visible.
Might not be needed for standard UI tho.
Also bring a good bunch of Charged Crystal Focii, they drop randomly and are
also sometimes on AH.
I had no help in the beginning, so I did maybe 10 tries before I made it,
but once you get the hang of it, you can farm it regularily.
Every now and then you get a nice item you can sell, maybe the Ring of the
Overseer or of course the badge. I got mine on the third kill.
Still farming it tho, hoping for some cash boost for epic flyer :)
If you are still not happy about this idea and rather would grind, I rather
recommend like other before me to grind primals. Nagrand, Shadowmoon or
Netherstorm. Primal Air usually sells best on my server.
I have killed quite a large amount of mobs around ogri'la and in the forge
camps, and in my experience nothing valuable ever drops. Some greens ofc, but
mostly crap.
However if you got skinning, make sure you visit the northern forge camp (Wrath)
for any demon business, there are a lot of skinnable dogs, and many people
just kill, loot and move on leaving the corpse up for taking (or more precisely
skinning :P).
Good luck in your endeavours.
