Jade Crane Chick

This pet is only available to Pandarens, you can learn it by going to your battle pet trainer in any major cities. You have to have picked a faction to get this spell, so your Pandaren must be at least level 11, or you have race changed. Another way to get the Jade Crane Chick is by buying it off someone. Each Pandaren can only get this pet once.

Blacklist Your Least Favorite Battlegrounds

I just found out about this, apparently it's been in since 5.0. You can exclude up to two BGs from popping up in your Random Battleground queue from the honor menu. To do this, open up your PVP menu, and hover your mouse to the right of the battlegrounds you want to exclude, you'll know it's blacklisted when there's a thumbs down sign next to it. For me, I chose to exclude AV and IOC, the two bgs that horde almost never wins at. Your choice of blacklist won't work if the battleground is featured as the Call to Arms.

Mage Bomb Macro

Playing a mage, I switch between the different bombs pretty often, when playing frost I like to macro the pet freeze in along with it. Instead of making three macros for each spell I do this:

#Showtooltip
/cast mage bomb
/cast freeze

Mage bomb will change depending on which talent you take.

Time to Hoard Those Lesser Charm of Good Fortune

According to this post, a new tier of charms called Mogu Rune of Fate will be used in the 5.2 raid. You trade for them with Lesser Charms of Good Fortune, just as you with Elder Charms. It hasn't been revealed how many Lesser Charms are needed to exchange for 3 Mogu Runes. Hopefully it'll be 90 or less. So if you're done with this tier of content, start saving up those Lesser Charms. Lesser Charm of Good Fortune is capped at 1,000,000.

Challenge Mode Gear Scaling

I've finally started to play around with Challenge Modes, here's some notes regarding gear:

• Gear will scale down to 463 but not up, so if you have any piece below 463 item level, it stays at that level. But if you have epic or upgraded gear, it will be reduced.
• Sha Touched Gems are deactivated, Tier piece bonuses are deactivated.
• Pvp stats do not get scaled down, not that they do anything for you.
• Your hit and expertise are not scaled down, bosses will be level 93, but most of the trash in the instance is only level 91, so you might want to consider reforging to not miss on level 91 mobs and put the rest into dps stats.
• While pieces with sockets have their stats scaled down an extra ~9%, the gems you place are NOT scaled down. Higher level pieces with multiple sockets will give you an advantage when scaled down compared to pieces without sockets.
• Along the same lines, enchants and profession bonuses do not get scaled down.
• Off topic, but mass res is disabled.

I've listed what I found to be helpful in the notes section for each boss and amended the LFR guide.

Kael'thas Solo Guide

The main reason why people are killing Kael'thas in The Eye every week is for a chance at the Ashes of Al'ar. If you don't care about the color and don't like the low drop rate, Reins of the Dark Phoenix is a similar mount. Read on for Kael'Thas guide.

Item Upgrades Not Available in 5.2

It's looking like item upgrades won't be available in 5.2 according to this post. So if you have anything you'd like to upgrade, get it upgraded now! Any conquest points that you have at the end of the season becomes honor anyways.
The upgrade npc will return in 5.3.
I wouldn't upgrade any honor gear though, it'll be better to buy new pieces. A fully upgraded piece of honor gear right now will be ilvl 466, according to this post, the 483 ilvl gear you can currently get with conquest will be changed to 476 in 5.2 when it will cost honor.

Eye of the Black Prince

I talked about part one of the legendary weapon questline here. 5.1 continues this storyline which rewards you with Eye of the Black Prince once completed.

If you've completed collecting your 10 sigils of powers and wisdoms and made your legendary gem, if not, refer to this.

Your next quest which you pick up from Wrathion is A Test of Valor. It'll take at least 6 weeks to complete if you cap your valor each week.
While you're doing this, you can start working on The Prince's Pursuit. You'll gain rep from Honored to Revered by killing players and npcs in the daily quest hub that's on the coast of Krasarang Wild. You don't need to be on the quest to get your rep, so get started on it while working on your valor.
After completing A Test of Valor you'll have two more quests.
Glory to the Horde requires you to win one of each of the new battlegrounds, Temple of Kotumogu and Silvershard Mines. I have a guide for the latter bg here.
The other quest is A Change of Command. You'll likely need a group for this since High Marshal Twinbraid and Warlord Bloodhilt both have 130 Million health.
Once you complete all this, you get The Soul of the Horde and the extra socket for your sha-touched weapon.

Onyxia Solo Guide

Onyxia was updated to be a level 80 boss in Wrath. You should kill her at least once for a 22 slot bag, as well as a soul cripplingly low chance at Reins of the Onyxian Drake. She also drops some updated tier 2 gear if you like transmogging things.

Malygos Solo Guide

Malygo's loot table only shows him dropping Reins of the Azure Drake, but based on my experiences yesterday, he also drops Reins of the Blue Drake, a drop from The Occulus.
Strats for soloing after the break.

T3 Gear on the BMAH has No Class Restrictions

Do you have too much gold to spend and want to look like another class? Well I have good news if you like tier 3. You can find pieces listed on the black market auction house occasionally with a starting bid of 10k. These pieces no longer have restrictions, there are no alternate pieces with the same design available for this tier of gear.

Cloth
Mage Priest Warlock
Leather
Rogue Druid
Mail
Hunter Shaman
Plate
Warrior Paladin

5.2 Ptr Available

The new patch is coming in 2-3 months and the PTR went up yesterday. You can find the patch notes here. The LFR version of Throne of Thunder will be 4 parts with 3 bosses in each wing, the minimum ilvl needed to get in is 486. Until then, don't forget to keep capping your valor for A Test of Valor.

Black Market Auction House Restock Time

I've been curious about the timing of the BMAH, this is what I have found out so far:
From 22:00 to 0:00 server time, items are restocked on the black market auction house. Items run from 12-48 hours, with most being 24 hours. It is possible for items listed as short in duration to go longer than 30 minutes, that is because these items are being bidded on, and each time there is a bid the timer is increased slightly to allow the other party to place a new bid.
