This is exactly what I came here to talk about!
Destruction AOE is so pathetically weak, that by the end of a Mythic+ dungeon, even a warrior tank will show as having done more damage throughout the course of the dungeon on particular damage meters. While nobody can even come close to the damage per second output of the Destruction Warlock on a boss fight.
Rain of fire does nothing. Tanks always move out of it, especially if there is Sanguine. It’s affect does not seem to stack either.
Cataclysm takes far too long to cast. Tanks always move out of it, and trying to cast it is a waste of 2 seconds.
Incinerate does so little damage that there is no point in using Fire and Brimstone.
Casting Havoc on a target in a pack of mobs gives too little affect.
It is possible to do some AOE, if you enter the combat with full Soul Shards, Havoc the biggest HP mob, cast Cataclysm, Rain of Fire and drop Infernal, then keep spamming Shadowburn and Conflagrate to generate enough Soul Shards to cast Rain of Fire again by the time it ends. But you are lucky to generate enough Soul Shards. For this you also need to use Soul Conduit and hope for some procs. If you are lucky you could also try to pin the mobs down with Shadowfury but it doesn’t exactly last long enough to make any difference.
What could be done about it?
Havoc needs it’s affect duration time to be extended, and I mean doubled. It also needs its cooldown to be reduced.
Rain of Fire should cost Mana. We have this Mana pool which never gets used unless we have to use Drain Life. We should not have to burn off our Soul Shards and exchange Chaos Bolt (the only spell we have that does any damage at all) for an AOE spell, which needs it’s damage topped up by Chaos Bolts to even appear like we did some damage.
Incinerate damage should be greatly increased. This would then give us a chance to actually do some damage in PvP, other than the damage of Chaos Bolt, which quite frankly just tickles Plate specs anyway. With an increase to the damage of Incinerate, then Fire and Brimstone might actually be a worthy option over Cataclysm.
Cataclysm casting time should be reduced to either instant cast, or 0.5 second cast. I think even 1 second would be too long if you have a Warrior tank who doesn’t like to stand in a Destruction Warlock’s AOE, because he wants to spam Details damage meter results, and show that by the end of an instance even he does more overall damage than the Warlock.
Shadowfury casting time should be reduced or removed. Shadowfury affect duration should be greatly increased. It helps Rain of Fire damage a little, to pin the mobs in place with Shadowfury… but again this takes too long to cast and by the time it actually hits, the tank has already moved the mobs away from the area in most cases of usage. Shadowfury should also have it’s time reduced to instant cast or 0.5 seconds at the very most.

Before people start to claim that “Destruction is overpowered in PvP”, or that “you must be doing something wrong if you cannot do more damage than a tank”… I must add…
Destruction Warlock is very broken for PvP. The times that you saw them win, they had the chance to smash you in the face with several critical Chaos Bolts. Chaos Bolts are the only spell that actually does some damage. With the new animation on them, and the extended casting time, we are waving a big pink fluffy flag and telling you that we are casting this spell. If you got hit by it, you are failing or on cooldowns. Destruction Warlock is primary target for all Mele classes who most often jump us in packs. We cannot PvP without a dedicated healer and tank to support our lives, or without the top pvp traits already equipped (Azerite armour).
Details damage meter is inaccurate! It also does not show “Damage Per Second Output”, it shows “Average Damage over Combat Time”. So whoever pulls first will show as having the highest damage on the meter. It is as simple as that, because that is how averages work. If you have someone pulling before the tank, they will show as highest damage. If everyone waits for the tank, he will show as higher than he actually is.
Recount however, shows “Real-Time Damage Per Second Output”.
People can’t seem to understand that Details does not show DPS Output, it shows AOT. If you don’t believe me, install Recount, and have Recount + Details running, then go and hit a training dummy for 5 minutes. You will see that after a period of time, details shows a 5k difference in supposed “DPS” readings, because it is not showing DPS Output. If in combat, the Warlock gets Mind Controlled, has to Combat Res a healer, or dies, or if the mobile tanking unit who can’t stand still goes out of range or line of sight too much, then Details will say that the Warlock did less than 10k “DPS” (AOT) while Recount will show that the Warlock was actually doing over 20k DPS.
Once people begin to understand how averages work, and stop thinking the Warlock did less Damage Output than the tank…
And once they make the other spells for the Destruction Warlock actually do some damage so that we don’t rely on Chaos Bolt for 90% of our damage… then Destruction Warlocks might actually get invited to do Mythic+ Dungeons, and not have to gain all of our armours from Raids Only.
