I feel like I’m really late to the party, because I really love the gnome heritage armor, and I’ve been doing the Gnome starter quest line as a way to grind some rep. I’ve also equipped the Gnomeregan tabard.
What’s the quickest way to grind rep for Gnomeregan?
Dungeons while wearing the tabard? Am I missing something to speed things up?
Equip a Gnomergan tabard (if I recall correctly you can get it from the quarter master in Ironforge near the flight master) and run dungeons.
I was exalted with Gnomergan on my Gnome by the time I hit level ~45 just by running dungeons alone with the tabard equipped
Grab the tabard and run BC or Wrath dungeons. Botanica is one of the best ones. Tons of mobs, lots of rep and it has a back exit so you can get in and out quickly. You’ll farm the rep up in no time just running that place over and over.
The quickest way by far is to have the tabard on and run Magister’s terrace on normal. It’s short, gives a good chunk of rep, and you also get shattered sun rep as well.
Can those dungeons be run multiple times per day? Or do you need to wait for a reset every 24 hours?
Equip your Gnomeragn tabard and clear Normal Shadow Labyrinth about 10 times. At the end of the dungeon, create a bogus premade group and then hit leave party. You’ll get teleported to the GY.
argent tourney in icecrown the champion writs 250 rep ea
A 5 min clear of Shadow Labyrinth nets about 3500 rep.
You can spam the normal dungeons, or run through all of the BC heroic dungeons one at a time. Doesn’t take long to finish.
This guy had rep (of course) long ago but on my Goblin he has on the tabard and runs heroic Wrath dungeons. Gather everything in the dungeon hit blood boil and poof they all dead.
Good luck!
equip gnomer tabard wait for the DMF if possible and pick up the rep boosters etc
I didn’t have any Alliance characters at the start of this xpac at all, now I have all heritage sets complete for both Horde and Alliance.
Tabbard and Wotlk dungeons are definitely the way to go, I do Utgarde Pinnacle because of the quick exit and I can fly down to the lower level and switch it up if I get bored.
Slap a Gnomer tabard on, and go blow through the BC Heroic dungeons. You’ll be Exalted in no time.
Here’s the heritage armor 
I did it! I just spammed Shadow Labs over and over and here I am! In all my gnomish glory!
FOR GNOMEREGAN!
