The Bottom Feeders: Moves You Never Use and Why.

[Thunda_Cat_SMASH]

This is off-GCD, free DPS. You need to be using it on cooldown regardless of AoE or single-target, Dark Arts buffed or not, its a part of the job's DPS rotation.

Is it really? I can see why in mobs, but for single target I'm usually sitting on a miniscule 1-2k MP, so using it will either drop me out of Dark side or prevent me using dark arts for another combo.

And yes I do use blood weapon and blood price on cool down.
