As someone who has been tanking as a warlock nearly every BFD lockout and can solo SFK I’ve been thinking about what end game builds are going to look like at level 60.
I think there is probably going to be 2 viable builds and going full Demonology for Soul Link is not one of those builds (even at 40 and 50); lest we get a rune which gives our Pets Avoidance (lots of AoE that will kill them) a rune which passively heals our pets when we do damage (otherwise pets will likely die from damage were sharing with them loosing Soul Link and Master Demonology), and a rune which makes Master Demonologist either usable with Demonic Sacrifice or changes what it does (the 10% phys dmg reduction from Voidwalker isn’t worth it when we will likely already have 60% from armor). Also healers probably won’t want to heal our pets.
So the builds I think will dominate are the following:
21/8/22: Going Siphon Life, Ruin and Shadowburn (for snap threat)
I think this will be the best build and will pull ahead with damage. With for the Affliction tree the 3 points of Improved Agony being changeable if warlock tanks will be expected to use Curse of Shadows/Elements in raid which I doubt because Agony is free threat.
In Demo the 3 points to Improved imp being free to change if Imp isn’t our pet of choice (I think it will be because Tank groups want Blood Pact) and can be moved elsewhere.
In Destro the 5 points in Aftermath can be moved to Improved Shadow Bolt (I think the Daze chance will be better than Improved Shadow Bolt as most of our shadow damage is from our DoTs)
21/21/0 Siphon Life, Demonic Sacrifice (9 free points)
The other build I think will pull ahead is a 21/21/0 build with 9 free points to spend picking up Siphon Life and Demonic Sacrifice (with intent we will be sacrificing our Voidwalker for the 3% HP heal every 4 seconds or Fire Imp for 15% more damage if Fire continues to be our primary spell school) assuming our pets have 0 chance of survival. I do suspect most will put 5 of the free points into Cataclysm but with HoTs like Demonic Sacrifice and Siphon Life and Drain Life (with Master Channeler).
7/21/22 DS/Ruin Flex Build (1 free point) (able to change to Fire Lock runes if you don’t need to tank a boss).
Alternatively a 7/21/22 DS/Ruin build might be a Dark Horse for maximum damage sacrificing the self heals we get for more damage and threat or for offtanking so we can flex into Fire Warlock runes if an additional tank is not needed.
Talents people think they should take but likely won’t be taken:
Aside from the aforementioned Master Demonologist and Soul Link here are a few talents I don’t think will be picked and why.
Intensity: I suspect we are likely going to get a rune which changes Hellfire (or the less likely Rain of Fire) into Immolation Aura while in Metamorphosis solving our AoE threat and not needing pushback reduction. Furthermore while channeling we lose the ability to dodge. However a dungeon build might take this for Pyroclasm’s 26% chance to stun if it works with the hypothetical Immolation Aura.
Destructive Reach/Grim Reach: We are already likely to be within 20 yards of the boss for Drain Life (24 if Grim Reach is taken) so it’s just dead points imo.
