As a warrior, pulling heavy in dungeons might seem like a good idea, but I see many who tend to just pull everything then use raw overpowers like a paladin uses flash while cycling cooldowns and waiting for the DPS to kill the pack. This is a bad habit to get into and not effective if you are in a group with low AoE dps potential.
If you prep the pull correctly you can make up for lower DPS by dealing massive AoE damage yourself and self healing the majority of incoming damage back up. Bare with me lots of numbers incoming.
Step 1 (The Basics): Switch to STR gear. You don't need 12k life for this stuff.
Step 2 (Preperation): Infuriate before the pull. We want infuriate to be available again while we are killing the group.
Step 3 (The Pull): Pick up the first few groups with flash to conserve tp. Refresh wrath stacks with HS > Maim > Eye if your stacks are low on time as you are passing through a group.
Step 4 (The Deeps): Bloodbath on approach to kill spot > HS (Unchained > Vengeance) > Maim (Internal Release > Zerk) > Overpower spam till unchained wears > Infuriate > Steel Cyclone (Pacified) > Flex.
Numbers
Vengeance: 50 potency x1, 90 potency x4 (assuming 3 sec between each enemy attack + zerk and maim bonus after first retaliation) 410 total
Overpower: 216 x 8 ((120*1.5 zerk)*1.2 maim) 1728 total
Steel Cyclone: 360 x1 ((200*1.5 zerk)*1.2 maim) 360 total
All ignoring defiance penalty so potency is true potency.
Total potency per target (ignoring HS > Maim prebuff damage and AA damage): 2498 potency per target in 20 second window with 16% bonus crit from wrath + IR.
Bloodbath Potency per target (ignoring HS > Maim prebuff damage and AA damage) 624.5 (equal to 2 unbuffed inner beasts worth of healing per target)
To get an idea of how much raw damage this will put out for you per target, use uncombo'd skull sunderer on a training dummy without defiance then multiply that damage by potency/100.
To include crit, take your crit chance, add 16% then divide by 2. So with only 14% base crit chance + 16% from stacks + IR we have 30% crit/2 = 15% damage increase on average.
2498 potency * 1.15 = 2872.7 potency including crit.
Example: Outside of party my 100 potency attacks deal 210 damage on average. Assuming only 14% base crit chance we end up with:
210*28.727 = 6032.67 damage per target over 20 seconds, or 301 DPS per target.
So remember always fully buff before overpower spam. It's not just for holding hate!
