I’m consolidating information I’ve found for easy access, none of these posted are my observation I’m just bringing it together so that you can see it all in one place. I will be keeping this up to date so feel free to check back, and report in this thread if there is a change or I’m just flat wrong on something I have. I’m not in the Beta, so I can’t clarify or test anything.
This is an up to date talent calc for MoP
The thing that may let Warlocks become a tank one day (fingers crossed) is this Glyph.
Glyph of Demon Hunting:
Demonic Fury now reduces damage taken instead of increasing damage dealt. In addition, while using Metamorphosis, Soul Shatter taunts your target, Twilight Ward will absorb all schools of damage and Demonic Slash is shorter range and generates fury.
In addition to what it says, the glyph does a few other things behind the scenes
*500% increase to threat generation while in Meta
*Meta no longer drains Demonic Fury
*Only the Hand of Gul’dan spell will require mana so there will be no need to ever life tap.
Now, according to the glyph, Fury now reduces damage taken instead of boosting out put. So lets look at Demo’s Mastery.
Demonology Mastery: Master Demonologist
*Increases the Demonic Fury bonus by X%.
*Increases the damage done by your demon servants by X%.
*The damage you deal while transformed into a demon is increased by X%.
-This last one now becomes: “The damage you receive while transformed into a demon is decreased by X%.”
This would significantly reduce damage received and make mastery a survival stat.
“But locks can’t block or parry” This is true but they can dodge and with 600% armor and all stats pointed toward mastery or dodge they are a match for any of the current tanks.
The community has proposed that an ability that converts spirit > dodge be created. This would both give meta tanks a way to gear dodge and make it so priests aren't the only ones using spirit.
But a tanks not just a tank because he can soak up damage like a sponge, no there is an entire kit attached and the Meta Lock tank is no different. It has an entire retinue to pull from.
*Demonic Slash: Tears at the enemy, instantly dealing X Shadow damage. This generates 30 Fury and has a 10 yard range. (reduce with the tanking glyph)
*Carrion Swarm (Passive): While using Metamorphosis, your Shadow Flame spell now costs Demonic Fury, interrupts spell casting and knocks enemies away from you.
*Immolation Aura (Passive): While using Metamorphosis, your Hellfire spell now no longer deals damage to you and does not need to be channeled.
*Fel Flame: Becomes Ray of Twilight, a line attack that does shadow damage and retains Fel Flames dot prolonging effect.
*Hand of Gul’dan: Summons 3 falling meteors on the target location reducing movement of all enemies in the targeted area by 15% with each meteor.
*Bane of Doom: Banes the target with impending doom, causing X damage over time for 1 min. When it deals damage it has a 20% chance to summon a wild imp
*Corruption: Deals X shadow damage over 18 seconds, generates 12 fury per tic
*Metamorphosis: Nether Plating (Passive): While using Metamorphosis, your armor contribution from items increases by 400%, the chance you'll be critically hit by melee attacks is reduced by 6% and the duration of stun and snare effects is reduced by 50%.
*Aura of Enfeeblement (Metamorphosis): Binds all enemies within 20 yards in demonic energy, reducing physical damage by 30% and increasing the casting time of all spells by 30%.
*Twilight Ward: Becomes Fury Ward, Absorbs X damage for 30 seconds at the expense of fury
*Unending Resolve: The Warlock hardens his skin, reducing all damage taken by 50% and preventing his spells from being interrupted for 12 sec.
*Dark Soul: Knowledge: Your soul is infused with demonic knowledge, increasing your Mastery by 30 for 20 sec. (30 Mastery would be a TON of mitigation)
*Health Stones: You know em you love em and now they come with multi-use charges
*Demonic Leap: Leap to the target location (no attack included)
*Provocation: your basic tank taunt
*Fear: becomes Sleep, (same effect, but the target stays in place)
*Demonic Portal: drop a beacon and port back to that beacon at will. (unconfirmed if this is usable while in meta)
