I read the following post http://www.ownedcore.com/forums/worl...xperience.html (Get 10% more Reputation/Experience) and it gave me an idea.
Ive been doing alot of this quest on my main Replenishing the Pantry - Quest - World of Warcraft I thought id use the extra 10% xp while its available and it does seem to stack with guild perk for xp. Ive instead of doing the repeatable on my main switched to my alt and have managed a level so far of hand ins with meat/fish i had saved up. Pretty sure if you had enough gold/farming time you could go from 85-90. Can't really do the math of how many handins it would take ( im not that clever or that rich to test it)
