There is so much wrong with this sentence that I barely know where to start. IB took 8 or 9 gcds to perform if you were starting from no stance.
First off there was absolutely no reason for WARs to stance dance in 2.0 (Paladins didn't stance dance either because incoming damage was high enough and constant enough that you wanted the damage reduction constantly when MTing). You were either MT in Defiance where you were building up Wrath stacks or OTing with Defiance off. Wrath stacks were initially the source of the Warriors increase healing, the Warrior either sat on 5 stacks of Wrath and had a similar amount of incoming healing as a Paladin or was 20% more difficult to heal because they had spent their 5 stacks to overheal themselves.They were meant to both be used for TBs. WAR gained the extra max HP, followed by a self heal to fill the newly obtained max HP. (aka, akin to TBN)
But PLDs could just sit in tank stance, leading to less dmg taken in prolonged dmg intake, and stack other CDs to make them too tanky, to the point SE had to change WAR to match what PLD could do. (PLD needed nerfed, not WAR buffed, as this ruined tanking mitigation forever)
During 2.0, if a WAR outgeared content they were pretty much invincible in Defiance, but if they did not the were incredibly squishy as the were primarily reliant of self-healing damage after it occurred and boss damage often outclassed their self-healing.
No... after the 2.1 changes WAR and PLD had similar ehp and healing received profiles. IB giving a 20% mitigation was actually the equivalent of the PLD's Rampart and is what let WARs survive T1-T5 tankbusters.Once WAR gained the -20% dmg taken, it made for an awkward scenario where WAR was essentially doubling up on its surivival, with both 20% more HP/healed amount, and 20% mitigation.
You are wrong. The introduction of Deliverance and Fell Cleave is what turned Defiance, Grit and Shield Oath into psuedo-cooldowns. Prior to 3.0, Warrior could not stance dance as you were required to be in stance to build Wrath and the moment you left it you lost all stacks. With the introduction of Deliverance and the fact it shared stacks with Defiance, swapping between dps mode and tank mode cost the Warrior nothing. Prior to that it took 7 to 8 gcds to fully activate Defiance.This is mostly why people started seeing IB as the TB CD that IR is today, but still saw PLDs tank stance as a stance, and not a CD.
No, it wasn't. People started using them as cooldowns with 3.2 due to the damage in A5S through A8S being tuned for tanks in i220 gear rather than tomestone/raid gear like A1S-A4S were tuned for. After you reached a certain average ilevel you didn't need the mitigation gained from tank stance to survive non-tankbuster damage anymore.HW tanking was designed around the idea tank stances were youre "Free CD" thats always available, if you didnt plan your cooldowns correctly, so it came at a cost." PLD being 2 GCDs for stance dancing, DRK was 1 GCD and MP, and WARs was a GCD and beast gauge for IB.
