5 Enhancement Shamans

[Apatheist]

Are you going to try doing dungeons with that team or just levelling through quests? Thinking voidwalkers would have trouble with AoE threat or perhaps not with Suffering on round robin.

A single voidwalker has trouble holding AE threat. 4 Voidwalkers can each focus on one mob and most packs are 3-4 elites. On single targets, they actually do a reasonable amount of threat if you give them a few seconds to cast a second torment before you start casting. You don't even have to assign a pet to tank non-elites because they'll be dead in like 2 seconds.

I set focus to a different mob on each warlock, send the pet in and then I have suffering, hellfire and prayer of healing on one hotkey. This uses the AE "taunt" to ensure all of your voidwalkers have some threat on everything before you start AoEing and even if the pets lose threat, you do so much damage with hellfire*4 that most stuff is dead in seconds (in earlier dungeons, at least.) I prefer the soul link build myself. 40% Physical damage reduction means even if my warlocks pull threat they can just tank through it.

While mostly at low levels, the dungeons will not be that successful later on I'll be able to steam roll through any content.

It's actually the other way around. 4 Voidwalkers trivialize low level dungeons when you're comfortable with pet management. 15-50 dungeons are super easy. Once you get to UBRS, Dire Maul, Scholo, etc. it's much more difficult because your voidwalkers HP/armor don't scale at all with gear. Some of those mobs hit very hard and have a lot more HP. As your gear scales, you do significantly more damage while your pets threat stays the same as it was when you first hit 60 so you have to be a lot more careful about pulling agro.

Pet tanking means you have 4 targets to heal rather than a single tank -- as well as having to top off your warlocks HP from hellfire and lifetap. The most efficient way is just to generally spam downranked prayer of healing once you get enough gear to sustain it. Since you can lifetap to full mana on the warlocks and one prayer of healing is generally enough to put them back on full HP, you really only need to buy water on your priest which is pretty nice.

All in all, it's not as good as a proper tank but it's still a fun comp and it's great for world PvP. Players inevitably focus on your priest first, which is fine because when your priest dies you get 10 seconds of free, uninterruptable healing and then soul stone res. If you macro accept resurrect with a hotkey to round-robin cast soul stone on your priest you can generally reapply soul stone before it dies again and spirit has no cooldown so you get another 10 seconds of free healing every time. Just don't apply all of your soul stones at once, because they'll all be consumed when you accept the first resurrection.

I always have a felhunter out when I'm PvPing. 30% Reduced damage from all sources plus 60 resist to all magic schools makes the warlocks super tanky and you can round-robin consume magic/dispel to completely negate AoE fear -- so you can pick orc instead of undead for the superior racial.
