Are my mitigation numbers off ?

So again, one of the claimed definitive advantage of PLD is, at best, flawed, at least, a blatant lie.

I can't say I disagree with you on that.

But Bulwark does have its uses outside of boss fights. Its boost to block rate is significant enough to be reliably useful when pulling a large amount of mobs in dungeons, for example.
