How get to Orgrimmar from 1st lvl Garrison?

I want to stop getting XP and need to get to Orgrimmar to Slahtz for this. How do I do it from 1st lvl Garrison?

I know that you can get there from Ashran. And people says that there is a portal to Ashran from west Mage building. There is Mage building at lvl3 Garrison, but I can't find neither it or a portal at lvl1 Garrson.

P.S. And I can't do any quests, because then I would lvlup to 91, which will mess up everything. P.P.S. Asking another player to help is not an option either.

Solution 1:

The "expected" way to return to Orgrimmar (or Stormwind!) from your Garrison, or anywhere on Draenor, really, is via Ashran. Khadgar warns you it might be awhile before you can return when you charge through the dark portal with him!

Level 1 and 2 Garrisons will provide access via a flightpath to Ashran, while a Level 3 Garrison will provide a direct portal. To the best of my knoweldge, this flightpath is unlocked as part of a level 91 quest. Alternatively, you may visit someone else's Level 3 Garrison and use it's portal to Ashran.

In addition, there are always the "class-based" methods of returning to Azeroth -- Mage / Death Knight / Druid / Monk self-teleportation, Mage Portal, and Warlock Summon, and "item-based" methods -- Hearthstone / Atiesh / Dalaran Ring / Guild Cloak teleportation, etc. As a level 90, you may even be able to use Dungeon Meeting Stones to be summoned to Mists of Pandaria areas (though randomly queuing through LFG won't do the trick).

Solution 2:

Given your constraints, as to what you can/can't do, your best bet is to pick up the cloak from your guild vendor to teleport you to Orgrimmar before you get to the garrison. If that is no longer an option the only way to get back is to get summoned or quest on. You can ask a mage for a portal, but you stated you can't ask other people for help. so you're sorta stuck.

Another option is to get the epic Dalaran teleport ring when you're lvling, and use that to teleport to Dalaran, from there you can take a portal to Orgrimmar.

Those are the 2 items I can think off that will let you teleport to Ogrimmar, without the help of other people.

Solution 3:

If you're looking for a creative way, you can always ask a warlock in Orgrimmar to summon you.

I'm making the assumption here that you already have access to trade chat in a first level garrison. I'm not sure anymore, I didn't pay much attention before I upgraded to the next level.
If you do, you can use trade chat to find someone, if no one in your guild can.

You can also party up with a mage, have them visit you in your garrison and make a portal.

Why prevent leveling up? Just curious :)
