Hey there, long time reader, first time poster.
Upon leveling my Hunter Twink, i've noticed that if you're on this quest (you get it in Hyjal, part of a quest chain):
Slash and Burn - Quest - World of Warcraft
you can mount the dragon and kill these mobs:
Fiery Instructor - NPC - World of Warcraft
The great thing is, you can kill as many as you want, they respawn very fast and die in one hit. If you dismount, you can loot them! This means you can kill all of them in around a minute or so, dismount, loot them (50-70 mobs), remount, do it again.
The mobs drop grey vendor trash and Volatile Fire!
Farm your Volatile Fire before it's fixed!
EDIT
After doing it on another Char, the mobs don't drop loot anymore, can anyone confirm if it still works?
Asked a Guildmember to test it, seems FIXED, but i can't delete the thread :/
