So for those of you just hitting level 90, read on for ten suggestions on where you can go from here.
Train flying for Pandaria. This will cost you 2,500 gold and will let you take to the Pandaran skies for easy transportation around the continent. It will also open access to additional content and daily quests -- but whether you're a fan of dailies or not, you'll probably want the convenience of being able to fly around. You can get flying from Skydancer Shun in Shrine of Two Moons (Horde) or Cloudrunner Leng in Shrine of Seven Stars (Alliance), both in the Vale of Eternal Blossoms. If you haven't yet done the quest chain to open up the Vale -- like my monk -- you can take a careful leap off the Serpent's Spine and then make a run for your faction's Shrine.
Get a Timeless Isle tour guide. Timeless Isle is, hands-down, the best way to gear up a new level 90 character -- with spec-appropriate epics that that can be found in chests or bought for Timeless Coins -- for whatever you might want to do next. However, island's inhabitants will prove a challenge for new 90s, so we recommend finding a better-geared friend or getting a group to tour around the Timeless Isle. Start by checking out all of the treasure chests on the island and then check out the tricks to get the chests that respawn every week.
Meet Wrathion. You've probably heard of this enigmatic character and the legendary quest chain he begins. The quest is very involved -- you definitely shouldn't expect to finish it immediately or even quickly -- but has lots of great rewards along the way. You can get started with the Stranger in a Strange Land quest -- or just go see Wrathion in the Tavern in the Mists in The Veiled Stair.
Farm honor in the Krasarang Wilds. Added in patch 5.1, there's PvP going on in Krasarang with three faction-related rares you can hunt and kill for honor, loot, and tokens you can turn in for more loot. If this sounds like a fun change of pace from battlegrounds, check out the details on WoW Rare Spawns.
Do dungeons, scenarios, heroics, and raids. Though you'll have to gear up to do the latest raids, dungeons -- especially heroics -- are great places to find gear to do just that. And because most players have been 90 for a while now, heroics and LFR can be easier because the rest of the group is geared up already.
Work on achievements. There are a ton of achievements out there and you'll have to pick which ones matter to you. Interested in in-game lore? Perhaps you should finish up your Pandaria quest chains and get Loremaster of Pandaria. Love pet battles? Maybe you'll want to work towards Legendary Pet Battler or World Safari.
And if none of these fit your taste? Well, that's the wonder of being at max level: you get to decide what you want to do next, whatever that may be. So have fun choosing your own destiny!
