Warlocks as tanks
Classically, the terms "warlock tank" and "drain tank" referred to an Affliction warlock with high damage to maintain aggro and talents that enhanced self-healing. Talents of note included and , and their combination with CC abilities like allowed the warlock to concurrently survive and deal damage to a large number of mobs. However, this type of tanking was never viable for instances and raids due to the lack of protection from critical hits and spike damage from bosses that melee.
Warlocks have also served as spellcaster tanks in raids. Due to now obsolete spell resistance, an appropriately geared warlock could act as the primary aggro target of a spellcasting boss. This usually occurred in council fights where other melee targets were handled by more traditional plate-wearing tanks (, ). This ability is not unique to warlocks, and mages have also stepped into tanking roles. Nonetheless, the emphasis on self-healing, the existence of threat-generating abilities like , increased health pool, and have always made warlocks highly capable of tanking.
In Mists of PandariaThe subject of this section has been removed from World of Warcraft.
The Mists of Pandaria expansion introduced the , granting a Demonology warlock a new form with increased survivability. In , the warlock gains:
- 10% physical damage reduction
- 15% magic damage reduction
- a that absorbs all schools of magic (instead of just Shadow and Holy)
- a Taunt-like ability
Like a traditional tank, Dark Apotheosis possesses many damage-mitigation qualities and the ability to keep aggro from other party members. Unlike designated tanks, warlock tanks are still missing protection from critical hits.
Historically, warlocks felt tankier than other casters and could even off-tank some encounters. We have made an effort in Mists to recapture some of that flavor. A warlock with this glyph should feel like they are about as effective tanking as an Arms warrior who pulls out a shield and swaps to Defensive Stance, or a Feral druid who goes into Bear form. You might be able to off-tank adds or pick up an actual boss for a short period of time if the tank goes down.To make warlocks an actual tank would take more significant changes. For example, we want tanks to have to pick up separate tanking gear than their DPS gear (this is even true of druids) and want tanks to have to give up some of their DPS potential in exchange for their survivability. In short, it needs to be a commitment, and that's the sort of thing that needs larger gameplay changes than just a glyph.
Despite Blizzard's attempts to dismiss warlock tanking as little more than a fun option with which Demonology warlocks could play around, there have been many reports of Dark Apotheosis warlocks tanking heroic instances and even raids (see video section). On the other hand, the relative difficulty of maintaining enough fury to avoid spike damage compared to using a Voidlord makes it highly situational, and pet tanking is still an important part of a warlock's PvE arsenal.
