You guys seem to thing cus it's random and has a small chance it's unreliable. On one hit, this is true (though you are more likely to block or parry than to fail to mitigate). The fights where any of this is relevant are all long fights. It will have good returns over time. ~45-50% isn't a small chance.


Which brings us back to high damage situations like solo tanking 5, 6, or 8. Sustained damage in these situations is so high, that at just about any moment, you could go down. (Even in full 2.0 bis twin would still occasionally hit me for 7000, cus and that's just bad luck.) if you get unlucky, no matter what you are wearing, you will die. But, if you wear 100 more parry, you will get that unlucky about 8% less.

How often is your 20dps gonna save the raid? More often than 8 in 100?

Is 20 dps worth loosing any amount of chance to cling to life and continue tanking?

100 secondary stats = 8% increase chance to parry, or 2% increase to group dps (at best).
