The header picture is actually a transmog outfit I've done up in MogIt for my paladin. I had a shield version for her protection off spec, but linking it on Twitter led me to this badass fel-green two-handed axe, which I just had to go get.
Then it hit me: I probably did the quest line on my warlock too long ago for Loremaster and vendored said axe for gold because transmogrification wasn't even in the cards yet. WTB a retroactive quest reward vendor, please!
If your warlock hasn't done the Cipher of Damnation quest line, for fel's sake go do it and grab the Torn-Heart Axe of Battle. This comment guides you through the whole thing. It's a long quest line that might take you up to an hour depending on how much you AFK through auto-flying, but the axe is going to be worth it in Mists of Pandaria.
Minors I would run with
Soon, Blood Pact will be posting the great spec guides everyone wants. The minor glyphs are split between the cool-looking and the functional. What mix of minors would a warlock pick?
Affliction warlocks will probably play with Subtlety if they want the old look or Verdant Spheres is they want to make mages cry. I'm tempted to stay with Unending Breath instead of Nightmares, since the combination of underwater breathing, waterwalking, and faster swim speed makes for a fantastic single-spell water travel option.
Demonology warlocks have been spoiled with options, but Shadow Bolt and Felguard have to be on everyone's cosmetic list. If Carrion Swarm gets much use in PvE, the glyph will be a must. Falling Meteor might be advised in encounters that have extreme knock-up effects, or if you haven't yet learned what happens when you chill on the cliffside of Lumber Mill's flag.
Destruction warlocks might flirt with Verdant Spheres but unfortunately don't have a lot of minor options outside of the general warlock glyphs. I imagine the fire of Nightmares will be a popular choice.
Honestly, demonology made out like a bandit in the realm of cool minor glyphs. Everyone's jealous of the Shadow Bolt splitting glyph -- most especially affliction warlocks, who are so used to using Shadow Bolt as a filler.
Carrion Swarm is the fel Typhoon spell demo 'locks get while in Metamorphosis. Like Typhoon, there's got to be a no-knockback glyph.
Falling Meteor modifies the amount of falling damage you take while using Demonic Leap. Now, when someone decides to give you water walking on Anub'arak in Trial of the Crusader, you can safely avoid dying.
Hand of Gul'dan reverts the new Hand of Gul'dan to the original beta Hand of Gul'dan that was targetable. Unglyphed, Hand of Gul'dan will land on your current target and it will follows that target anywhere, circling around like a shaman's elemental shield. Glyphed, Hand of Gul'dan will be placed with a target circle and will remain where you put it even if mobs move.
Shadow Bolt is the popular glyph that splits the filler spell into three. It's not just cosmetic but actually splits the spell into three smaller bolts, each of which can crit by itself. The glyph applies to all the filler spells a demo 'lock would use: Shadow Bolt, Soul Fire, and Touch of Chaos (Meta).
Sadly, they haven't made it available to destruction, because I suppose three mini Chaos Bolts is just too fantastic to have.
Subtlety and Verdant Spheres are two glyphs that go together. Trying to have both glyphs active results in one empty glyph slot and Verdant Spheres active. Subtlety results in the classic no orbs or shards around your head look, while Verdant Spheres gives you Kael'thas's fel-green balls.
Subtlety is specifically for affliction, but Verdant Sphere can be used by either affliction or destruction.
Please email all your Kael'thas transmogs to me with this glyph active so I have plenty of mage-trolling material for future Blood Pacts.
Crimson Banish is exactly that: When you Banish a demon or elemental, the mob has a reddish tint instead of the normal yellow-green one.
Enslave Demon remains as boring as ever, shortening your Enslave Demon cast time by about 1.5 seconds.
Eye of Kilrogg is nice for mountain climbing, but I don't see why you wouldn't otherwise fly up there yourself to place the portal. I suppose the main attraction is that you can place your portal elsewhere without actually moving yourself.
Health Funnel is an interesting change. Instead of channeling health to your demon, you instantly restore health, with an added cooldown on the spell. It was a great leveling minor glyph for me.
Nightmares is another fun, functional glyph that looks amazing. Glyphed, you can run across water on your Dreadsteed or Felsteed, and as you run, fire will trail from your steed's hooves across the water. There used to be a trail of fire in the wake of your steed, but for now, even high graphics settings aren't showing it, so it could be bugged.
Soulwell has changed from the mana cost reduction to a simple cosmetic glyph. When you summon your soulwell, it lands on a big green rune and smokes green smoke from the top of the well.
Unending Breath is the same old faster swimming glyph that it's been. Since we have no Vashj'ir zone to make guildmates grateful for this glyph, it might fade into obscurity since I bet battlegrounds will use Nightmares more.
"Hunter weapon? That's totally a warlock weapon."
Don't worry: I didn't forget about Glyph of Felguard. Save the best for last, right? Read it and rejoice: "Your Felguard will equip a random two-handed axe, sword, or polearm from your backpack."
I can transmog my felguard's weapons?! Yes, you read that right.
What weapons again? Only two-handed options apply -- axes, swords, and polearms. Pictured to right is a felguard with the two-handed sword Obsidian Edged Blade.
What about the Wrathguard? Yes, it also applies to the Supremacied demon upgrade, and you can change both of his weapons. If you want to dual-wield the same weapon in each hand, you'll need two copies of the same weapon. If you have only one weapon in the backpack, then it only changes his main-hand weapon.
"Maximum of 16 total weapons" The wording is precise, meaning that only weapons from the original backpack bag can be chosen by the glyph. This can stand as another reason to cry for a size upgrade on the backpack or it can help limit your weapon pool so your favorites surface more often.
So many choices! My personal favorites that are piling up have a Burning Crusade ring to them, which makes complete sense considering the mass of demons in those zones. Hellreaver, Torn-Heart Axe of Battle, Gladiator's Decapitator, Gorehowl -- all Burning Crusade and easily soloable even now. But if Bryntroll, Lord Marrowgar's ice axe from Icecrown Citadel, is more your thing, I completely understand.
If you want more weapons from different expansions, WoW Insider commenter Revynn has written up his favorites from classic, The Burning Crusade, Wrath of the Lich King, and Cataclysm.
If you have other favorites, send me an email at firstname.lastname@example.org and somewhere down the line there can be a Best-Dressed Felguard with matching master transmogs edition of Blood Pact.
