New eight-boss Mythic-only mega-dungeon.

Augmentation is a damage dealer role that uses the essence of the Black and Bronze dragonflights to amplify the abilities of nearby allies.
NEW BONUS EVENT: KALIMDOR CUP
Rediscover Kalimdor's skies with a new dragonriding racing event arriving to Azeroth and running from August 15–28. Challenge 16 races across Kalimdor in Normal, Advanced, and Reverse variations to earn Riders of Azeroth Badges to exchange for rewards from Maztha.
THE WARLOCK CLASS EXPANDS TO NEW RACES
The Warlock class is now available to Night Elves, Draenei, Lightforged Draenei, Pandaren, Kul Tiran, Tauren, Highmountain Tauren, Mag’har Orcs, and Zandalari Trolls. You’ll also be able to undertake a new Warlock-specific questline and use the Barbershop to customize your pets.
GRAPHIC UPDATE
Updated the lighting and fog throughout Kalimdor.
- Added 5 new fur colors for Worgen.
- Added 1 new eye color for Mag'har Orc.
- The light source that reflects in non-glowing eyes is no longer static.
- All restrictions for unlocking Allied Races have been removed, with the exception of a level requirement.
- All Allied Races can now be unlocked once you have a level 40 character on your account (was level 50).
- Newly created Allied Race characters will now be directed to Chromie (was the Warboard).
- Characters level 10–60 that have not been logged into for 60 days will now have the option to receive a Welcome Back Gift on the character select screen. The Welcome Back Gift includes:
a. Select a specialization upon log in to become equipped with updated bags and gear that is appropriate to the character’s level and selected specialization. All previously worn items and bags can be collected from the mailbox.
b. Teleport to the character’s home city of Orgrimmar or Stormwind.
c. All quests in the quest log will be cleared to provide a clean slate. To continue your leveling journey, head to Chromie in Orgrimmar Embassy or Stormwind Embassy.

Level 10 - Apprentice Riding
Level 20 - Journeyman Riding

- Characters that reach level 30 will receive the quest “Time to Fly” and be awarded with a flying mount: the Harbor Gryphon for Alliance characters and Scarlet Pterrordax for Horde characters.
CLASSES CHANGES
There are A LOT of classes changes. I would suggest reading the post from Wowhead as it would take me forever to list them all here. The link is at the bottom.
ITEMS AND REWARDS
Players will now be able to trade items and gold directly to characters on other realms in their region. Previously this was limited to things like conjured items or eligible raid/dungeon loot, but all those cross-realm restrictions will now be lifted. Play with your friends and trade whatever you want to whoever you want!
PVP
Like classes changes, there are too many changes to list them all here so I'd suggest reading the official Wowhead post. Link below.
