TY for your input Nano,
I have gotten the hide to drop 6 times so far, but the problem is that after I get one drop, it will not drop again until the server restarts. All 6 hides that I've gotten so far were received in less than 10 kills, and after the turn-ins I have killed HUNDREDS of yetis without getting another to drop. After the server restarted I got one again on LITERALLY my second kill. I think that the drop table is not identifying the item as being a repeatable quest maybe? I don't know, I just know that it's impossible that I can go from getting it in less than 10 kills after server restart, to killing over 300 yeti's and never seeing it drop(until server restart, then it drops again).
This is frustrating because it's my only method of farming darnassus rep besides Morrowgrain(which I can't afford lol).
If anyone feels like helping to confirm this, go kill a few yetis and get the "Pristine Yeti Hide"(or "Perfect Yeti Hide" for horde) and turn the quest in; then go back and kill as many yeti's as you can stand, and let me know if you manage to get another one without the server restarting.
update: Today I got my first hide on kill #6, then killed 10-15 yeti's before server crash without a hide. Logged back in and got one on my second kill. Wish I could use the bugtracker.. :/
