The Krokul (broken draenei). Why? Because they are AWESOME! They can be rogues and warlocks! Two classes that draenei cannot currently be. They have back tentacles which would be unique to their race. The Broken would make a strong ally to the alliance, strengthen the draenei lore, and give the ally players a new monstrous race that we deserve.
The broken were also the demon hunters. 
Sethrak. We’ve got all manner of mammalian races; now we need some reptiles.
I would like two races added to the game. First is the Leper Gnomes. They would use the Gnome models, but be green.
The Leper Gnomes, in Classic, have some members already part of the Horde as some of them work in the Under City. Take this NPC for example:
Apprentice Crispin, along with Ganoosh, and Jennings are in service to the Forsaken. On his lore page this is said “Crispin said that Ganoosh had “bent the knee to the Banshee Queen, thus making him one of us””
One of the Forsaken even make fun of their height. So, naturally, they’re part of the Horde already since alliance make fun of Gnomes all the time. I’d really like them to be a counter-part to Gnomes like the Nightborne are to the Night Elves.
The second race would be the Eredar. With the Burning Legion pretty much in ruins and without a leader. There are many unemployed demons. They dislike the Draenei, so I imagine the Horde could take them in on the basis that the Alliance took in Void Elves. This one would be harder to do, but I really just want red draenei.
Ogres, Mogu and Man’ari.
Arakoa and Saurok
FUZZY FOXES!!! – ̗̀ (ᵕ꒳ᵕ) ̖́-
They can set up camps anywhere they want and log out for rested EXP, and then teleport there ANY TIME THEY WANT like an extra hearthstone! They are so cute! If you level one up from level 10, you get a DRINKING GOURD for a cape! They can be Warlocks and Death Knights and everything else except Druids ( 
) and Demon Hunters and they’re just so cool and smol and I love them with all my demony heart. They have llamas like Dolly & Dot, and they will be your best friends. They have little paws and triangular ears and they fight for the Horde which is the best faction.
Play them!
Only if Horde get Hozen.
No, Jinyu - Hozen.
Stoneborn. Because Gargoyles holding swords is really cool.
Since no one else is saying it:
Hozen
Faction: Horde
Classes: Warrior, Hunter, Rogue, Shaman, Warlock, Mage, Monk, Death Knight
Racials:
Dooker-Ook - Identical to the Kul’Tiran racial “Haymaker.”
Hard Rock - Hurl a rock at an enemy, dazing them. 1-minute cooldown.
Idol Hands - Use rudimentary tools to construct a primitive idol that will Fear low-level enemies so they don’t aggro you. 30 second duration. 5-minute cooldown.
Going Ape (Passive) - +5% base movement speed, can double-jump.
Racial Mount:
Either the Krokul as mentioned earlier or Sylvari… I need a skinny Draenei male model, the armor just doesn’t look good on the fridge body type.
Totally agree, especially how in the MoP story Hozen helped Horde and Jinyu helped Alliance.
Helfs for the alliance ofc.
Vrykuls
Hear me out.
Gnome.
But Void.
With pointy ears.
Okay so here’s my idea.
We’ll make this super cute race, and let them pick whichever side they want to play on, so it’s not lopsided. They’ll be the most adorable and most perfect race in the game. It’ll be great. We can call them Pandaren.
Yeah? Yeah? Who’s with me?
I vote we call them Vulpera.
I vote we delete void elves.
I vote we delete Pandaren.
I hear they make good burgers.
isn’t delete and void kind of the same thing?
I would really like ogres to be a thing already. And I’m not a fan of horde… But I would love to play one.
Honestly, it’s a long shot in hell: but I would kill for Stoneborn.
Stoneborn are denizens of the Shadowlands, born and raised there. It’s not like they’re the souls of people who have died and moved on and it would be wonky for them to come back to a living realm. It would be them traveling beyond the Shadowlands, and if we’ve learned anything from the Dreadlords (who are made in similar ways), them being outside the realm of death is totally doable.
There’s a male and female model, they have the potential for awesome racials, and we’ve seen casting animations for both male and female versions of the skeleton. Could be awesome. Only problem is they’re a bit big, so we’d need to shrink them a tad. Maybe make them Zandalari height.
