This guide is intended to get you from 85 to 90 efficiently with an eye towards gearing for raiding. If you want to complete every zone and savor every quest, this guide is not for you.
In Pandaria quest rewards are class specific. If you are leveling in a spec that is different from the spec that you will ultimately be raiding in, that is no problem. As you approach 90 you may be offered a choice of gear and you can pick what is appropriate.
Level 85 - Getting Started
To start out in Pandaria, visit Grommash Hold. Here you will pick up a quest that will take you to the Jade Forest. Level through the Jade Forest until you hit 86.
Level 86 - Learn to Farm
Once you hit 86, cross the bridge into Valley of the Four Winds and start questing at Pang’s Stead.
You will level through Valley of the Four Winds and Krasarang Wilds until you reach 87. In Valley of the Four Winds you may stop once you reach Halfhill and open up cooking and farming. This will give you access to the Tillers dallies at 90. In Krasarang Wilds you may stop once you have finished the Red Crane quest line. This will enable you to access the August Celestials dallies at 90. Keep questing in either zone until you hit 87.
Level 87 - Isn't Leveling Fun!
Once you hit 87 head to Grassy Cline in north east Valley of the Four Winds and climb the veiled stair.
There are a few quests here along with the Tavern in the Mists and the Black Market Auction house. Work through this to Kun Lai Summit. You may stop once you open the gates to the Valley of Eternal Blossoms. The quest to open the gates can be picked up at the Temple of the White Tiger. You won’t quest in the Valley of Eternal Blossoms at this point although you can go to your faction city, get the flight point, and have access to the bank, portals, trainers, vendors, etc. Quest in Kun Lai Summit until you hit 88.
Level 88 - Almost There
Once you hit 88, head to Winter’s Blossom and work your way down to Townlong Steppes.
You may stop questing in Townlong Steppes when you open up Niuzao Temple and the Tier/Justice Point/Valor Point vendors. Quest in Townlong Steppes until you reach level 89.
Level 89 - The Final Push
Once you hit 89 make your way to the Dread Wastes.
Questing in the Dread Wastes should take you to 90. As you get closer you will start picking up quests that awards level 450 gear. Unless you have found the equivalent from a rare or a dungeon you will want to make sure that you get these.
Dungeons - Bored with Questing Now
There are four dungeons available while leveling.
Temple of the Jade Serpent & Stormstout Brewery: You only need to do these once to complete the quests.
Shado-Pan Monastery & Mogu'shan Palace: Level 435 gear drops here which is useful while you are trying to gear up. This combined with the 450 gear you can get from Dread Wastes quests should put you in the ball park to start Heroic dungeons at 90 which require 435 iLevel.
Level 90 - Time to Gear Up
Check your iLevel. If it is below 435 run Shado-Pan Monastery and Mogu'shan Palace for more gear. If you have not yet finished the Dread Wastes quests, do so.
Once your iLevel reaches 435 you can run Heroic Dungeons which drop 463 gear and a chance at 476 epics.
Pick up the quest The Arena of Annihilation from Gurgthock at the Temple of the White Tiger. Queue for and complete the Arena of Annihilation scenario. This will get you a 463 weapon. Running other scenarios gives you a chance at other 463 gear.
Get in a group to kill the Sha of Anger. When he is dead loot him. This will get you the quest Remnants of Anger which gives 476 boots. If you can, get in a group to kill Galleon for 496 gear.
Check with friends, guildies, and the AH for 476+ crafted gear. If money is not an object, check the BMAH for occasional epic gear.
Do dailies for rep and Valor Points. You will start with the Golden Lotus and Klaxxi dailies. Once you are revered with Golden Lotus you can start Shado-Pan and August Celestials dailies. Earning rep with these factions will allow you to buy gear (among other things) with VP. Dailies for the Tillers, Anglers, Lorewalkers, and Order of the Cloud Serpent also grant VP.
Dailies also grant Lesser Charm of Good Fortune. Once a week 90 of these
can be redeemed for 3 Elder Charm of Good Fortune which can be used for
extra loot rolls when raiding.
You can use Valor Points to buy gear from the Golden Lotus, Klaxxi, Shado-Pan, and August Celestials factions. The weekly VP cap is 1000vp - so make sure thet you VP cap every week. You can get VP from dungeons, dailies, scenarios, LFR etc.
Looking for Raid
Once you reach iLevel 460 you can access Mogu'shan Vaults through LFR. At iLevel 470 you can access Heart of Fear and Terrace of Endless Spring through LFR.
