-Warlocks cant parry, and have minute dodge
Well if they want to tank, this has to change.
-Molten Core also affects Immolate
No mana cost on immolate is a pretty useless talent
-Searing Pain->Incinerate->Searing Pain, fun multiple instants
You want GUARANTEED instants, not ones you hope for
-Kick is Mind Freeze is Shield Bash is Skull Bash(-15 yards). Demoralizing Roar is Demoralizing Shout
And there are no unique abilities in your spec AT ALL.
-Essence of Darkness is open to any tree, PVP much
-Demonic Pact is there to retain raid utility
But nobody will take it unless they are forced to because it provides no benefit to the warlock
-I made Twilight Infusion low to keep low level warlocks from getting to much scaling and to make non-demonologists not recieve that much. Metamorphosis armor=more spell power
Without high scaling they will be rubbish tanks who die quickly because they don't have any armour
-Dark Grip: People have multiple ability schools, plus Improved Kick
-100% cast time lost would not be balanced
Yes it would, because otherwise you can't tank at all because all of your spells would be delayed by the boss you have aggro on.
-Low dodge no parry for spell casting avoidance
YOU NEED THESE OR YOU CAN'T TANK.
-Haste is more spells, crit needs a look over, mastery is more shield for less damage taken. Death Knight Mastery
You can't cast non-instant spells as a tank!
-Dark Curse is weak.
Yes it is. Fix it.
-Felflame is meh, I had worked it into alot of talents but finally removed it because
you dont get it till 81
-I looked into damage generating mana, but left it up to Improved Soulburn and Void Skin. Life Tapping is not noted and would be stupid to use
These aren't enough for current demo warlocks, why would they be enough for one that is tanking? Tanks can't afford to be worried about going OOM
-I looked into Death Coil too, I had it restore flat health (like Rune Tap) if the target was immune to horror effects, but removed it for Improved Soulburn
Why?
-Shadowflame is the main AOE move, I guess i should've buffed the damage. Maybe in Crossfire? Felflame is not necessary because Immolate has no effect on the target other than damage
-Hellfire is debatable
No it isn't. TANKS CAN NEVER AFFORD TO CHANNEL.
-I had pet damage heal you for a percent of its damage, and then any overhealing was converted into a shield. I prefer the current mastery now because its not dependant on pet
