Darnassus non-repeatable quests at high levelFollow

Hello,
I am a level 54 gnome lock trying to get up to exalted like every other non-elf on my server. I am a 300 alchemist and am getting sick of morrowgrain and runecloth. Does anyone have any ideas for some NON-repeatable quests for Darnassus faction at my level? I can't seem to find any zones that give out darnassus rep past desolace. Also, if anyone knows any mobs I can grind for faction, that would be awesome...the shadowprey village guards didn't work. I know this is probably a repeat post so if anyone has a good link to another post that would be cool too. Thanks so much!

Other than the Morrowgrain turn ins and the Runecloth turn ins for Darnassus, there are no other non-repeatable quests for Darnassus that you can do at your level for rep. No matter what you do, how you go about it, reputation grinds are just that, grinds.

Good luck.
