Warlocks are very powerful enemies for every other twink class in 29 bracket. Top spell damage warlocks can have over 160 spell damage making them dish out lots of damage. Warlock's DoTs are devastating, and can kill almost anyone when correctly used. This is why DoT-runner warlocks are usually on top of damage charts. Warlocks are very powerful if you have correct play style and gears. Warlock is very gear dependent so you should go for best gears possible.
