Lets nerf WAR :D

[Aurelinaus]

Yet most peoples here only talk about SwO buffs when real problem is in tank stance, SwO damage is more than fine its the ShO that lags behind coupled with lower enmity modifiers like you said. Now if penalty was roughly same as WAR/DRK and modifiers got fixed alot of issues would propably go away, only real issue left would be clunky stance swapping due GCD but that can be dealt.

Quoted figures are incorrect WAR tank stance penalty is penalty 12%, PLD tank stance penalty is also 12% not 20%, they completely forgot about FoF. DRK stance penalty is correct though.

Edit: also PLD does not have lower enmity modifiers they are the same it is the combo'd potencies that are slightly lower (e.g. Halone potency is 260, vs BB's 280 before buffs), and I am still wondering how that correlates to lower tank damage since out of the 3 finishers one is a DoT, and the other two branch off the enmity combo.

As opposed to what? Their unbuffed base damage that they should never be doing?

Assume Base = everything excluding Sh/SwOath, Grit, Darkside, Bloodweapon, Defiance, & Deliverance

PLD Base = Roughly 7947 potency
PLD SwOath = Base+1440 potency; Roughly 18% damage increase over Base, or 118% of Base as Max.
PLD ShOath = 80% of Base damage, a 20% loss. Or [1-(0.80(ShOath))/1.18(Max))]*100 = 32.2%
Therefore Shield Oath is a 32.2% DPS loss compared to PLDs maximum damage in SwOath.

DRK Base = 1
Darkside = 1*1.15*1.0375(Bloodweapon); A roughly 19% increase over Base, or 119% of Base as Max.(ignoring BW MP bonus)
Darkside+ Grit = 1*1.15*0.80 = 0.92; An 8% decrease from Base or [1-(0.92(Grit)/1.19(Max))]*100 = 22.7%
Therefore DRK loses 22.7% of Max DPS by turning Grit on, ignoring Bloodweapon TP/MP bonuses.
No Darkside + Grit = 1*0.8 = 0.8; A 20% decrease from Base or [1-(0.80(Grit)/1.19(Max))]*100 = 32.8%
Therefore DRK loses 32.8% of Max DPS if Darkside drops while Grit is up. Actually more if it's down when certain abilities are off CD.

WAR Base = 1
Deliverance = 1*1.05; A 12.5% increase over Base, or 112.5% of Base as Max.(Crit bonus assumed [(.00+.02+.04+.06+.08+.10)/6)1.5] = 7.5% for simplicity)
Defiance = 1*0.75; A 25% decrease from Base, or [1-(0.75(Defiance)/1.125(Max))]*100 = 33.3%
However Unchained = Base 16.6% of the time.
0.3333(Defiance Loss)*.8334(%time without unchained)+[1-(1(Base)/1.125(Max))]*.1666(time with unchained) = 29.6%
Therefore WAR loses roughly 29.6% of Max DPS if Defiance is up, ignoring the higher potency abilities of Deliverance.

Feel free to correct my math, it's past 3AM for me. The initial poster was on the right track, but holy hell there's so much misinformation going on about tank stances. FoF, Darkside, Berserk, etc do not get to count against tank stance when you have access to them out of tank stance. 1*0.8 & 1000*0.8 are both going to see a 20% loss. Yes this could potentially be offset by ability timing lining up with buffs like Unchained and/or breaks during ability down time. Those variables would be specific to certain fights, and average out in theory. If you would like to simulate 10 minute rotations by fight that might be interesting to see. However, that still will not change the 0.80 modifier on stances.
