I like the Raptor Mastery quest, along with all the others from Hemet Nesingwary, mostly because all the mobs are in one spot, and they give nice hides every time! :)
Easy way to finish this quest is to run to coordinates 25, 15 and put your tracking on beasts. If you are capable of killing these raptors, then you can certainly handle the tigers and panthers in the area too, which makes the second part of those quests a natural combination if you are speed leveling.
And, oh...the hides! Plus all the hides from the Young Stranglethorn Tigers and Crocolisks on the way back to Nesingwary's camp...no wonder I was able to get my mount at Level 30!
My usual method of attacking is to set Hunter's Mark on the target and send the cat in. As soon as the cat has aggro, I do one Arcane Shot and let Auto Shoot take care of the rest. If the Raptor leaves the cat I hit it with a Concussive Shot and start backing up (watching for mobs behind me on the inset mini map), and let the cat damage it while it tries to get to me. Sometimes they do make it to me, but by then they are nearly dead. Other times the cat gets aggro back and the deal is done.
All in all, a fun and easy quest at 31.
