5 warlocks any good for pve ?

they just dont have the dps to last, plus I'm not sure their pets could tank heroic bosses very well.

That.

You just can keep the pets alive vs bosses. Maybe with a very complicated cycle in summing pets you could manage to kill HC bosses. Like always making sure to have atleast 1 VW(voidwalker) alive, so summon a new one on slave 2, when the VW from slave 1 dies. When the VW from 2 dies, 3 summons one.

And have a severe cripple on dps.

And with no healing really beyond life drain...

I can't see 5 locks getting too far.
