Why Avoid Parry?

[Kosmos992k]

So why should tanks avoid Parry, and why is the advice to new players to avoid it?

Because SE screwed up tanks in 3.X. In the interests of scaling (apparently) both Parry and blocking were treated to huge nerfs in effectiveness and more or less capped in terms of what they can do. The impact of Parry was scaled down so much that it's of extremely limited use now, despite all our tank gear dripping with it.

Thinking about the PLD for a moment, PLD is supposed to be the mitigation tank, and yet not only did they screw up Parry, they screwed up blocking, and now further compromised the usility of blocking with the changes to Shield Swipe. So, almost all the extra mitigation PLD has, has been seriously nerfed.
