Tank DPS Ranking prediction.

[Ipkonfig]

FoF is decent, 30% damage for 30s on 90s CD, 33% uptime for an overall damage increase for around 10%.

I guess DRK's "Sword Oath" is Dark Side, 15% constant damage increase, which can be up while in Grit. They also have Blood Weapon which is 10% attack speed and MP/hit for 15s on a 40s CD. Makes TP sustain rough.

Zerk is an amazing DPS cooldown if you have a good healer who can dispel the pacify right as it lands, but on average all of WARs potencies are really low, all three combos for them average at or just below 200, Fracture for them is only 300 potency, and the only OGCD they get is Brutal Swing for 50 potency every 20s. The saving grace is Maim + Deliverance giving them 25% more damage and the 2% crit per stack of Abandon and Fel Cleave hitting like a truck.

Another thing to consider is that DRK has 5 OGCD attacks to factor in.

Low Blow - 100 potency
Salted Earth - 525 potency
Dark Passenger - 150 potency
Plunge - 200 potency
Carve and Spit - 450 potency with DA

DRK will have fantastic tanking DPS as well, Dark Side running while in Grit helps stop the DPS loss on the stance, and Low Blow has a 30% chance to reset on Parry. Dark Dance has a 33% uptime... SO MANY KICKS!
