But, if the stances were innate, then how would they apply the unnecessary defensive skill penalties? Meanwhile, on Test... Phalanx of One: "Reduces incoming damage slightly. Has a chance to proc Phalanx of Fury when struck in combat." Permanent buff with no buff timer, and has a 5 second recast timer. Defensive Proficiency interaction: Proficiency completely overwrites the Phalanx buff. Cannot cast the Phalanx buff while Proficiency is active. Other than the unfortunate loss of the Phalanx of Fury, this looks to be working as intended. Dual Wield Proficiency interaction: Both the Proficiency and Phalanx buffs can be up at the same time. It does not matter which is cast first, they do not prevent each other from being cast. This seemed odd, so I did some quick parsing to check if the defensive bonuses were stacking: they are not, I received the same min and max hits. Not sure if it's intended that both buffs are on at the same time, but that puts Dual Wield as the multi-mob tanking setup now to take advantage of the Phalanx of Fury procs, except that this tanking Proficiency still has a counter-intuitive 40% dodge skill penalty. 2-Handed Proficiency interaction: Activating the Proficiency removes the Phalanx buff. Once the Proficiency buff is on, you can cast the Phalanx buff. This happened every time, regardless of whether I was switching out of another weapon stance, if I was recasting the 2H Prof even though it was already on, or if I had no Proficiency on at all before casting Phalanx then 2H Prof. I also tried two different weapon types, slashing and blunt, with the same results. I am going to guess that 2H Prof is not supposed to remove the Phalanx buff, and this is a bug. No Proficiency interaction: Activating Last Stand discipline overwrites the Phalanx buff, and I cannot cast the Phalanx buff while that defensive discipline is running. However, Phalanx now suffers the same problem we were having with Defensive Proficiency: no overlap allowed. Once Last Stand fades, there is a period of time where no other mitigation is active other than the base 5% for being a Warrior. And because of server time syncing, you may have to wait a tick or two before being able to cast Phalanx, DW Prof, or Defensive Prof. That time gap matters during raids, and so far I have had to compensate for it by using Flash of Anger for the time between mitigation buffs. That wouldn't be necessary if these were working innate passives. Speaking of raids, taking an additional 10% damage from Commander Galenth and Captain Kanteer promises to be... fun.
