XIV WAR Tanking - Baseline Mitigation and PLD comparison

[RougeBuffle]

This beyond my ability to judge. [...] If there is a class, regardless of mechanics, which is unable to complete the job required (e.g. a DPS which fails to deliver enough damage to prevent healer OOM, such as using a WAR as a DPS), then it is not viable. A viable DPS may be clubbed by a special mechanic, but it is otherwise fine. WAR is not being hit by any special mechanic, it's just failing to do the task assigned it.

So... WARs can be at times, "clubbed by a special mechanic" but are otherwise fine?
What 'task' are they failing to do? Who assigned that 'task'? You?
Isn't all of this beyond your ability to judge? What Coil experience do you have?

Of course Two PLDs can clear everything, they are the bread and butter... one sided pure defensive tanks.
Doesn't change anything to the fact that a PLD/WAR duo can also clear everything... and, I'm sure, 2x WARs can clear at least Turn1/2.
{With 2x BRDs for turn 2 obv}

WARs are viable, end of the story.
