If Parry Is Removed

[MiniPrinny]

Either way won't change much, because the Parry mechanic itself is probably never better than even the smallest increase in DPS via Crit/Det,

As a Dark Knight main, I'm shocked to see you damn the mechanic itself. On average, I have a 15-20% parry chance each raid night, that's 3-4% less physical damage that I'm taking overall and 5-7% chance to counter-attack with a free Low Blow. The power of parrying is underwhelming when you're playing, but when you look back at the math, you'll see it as a very powerful part of any tank's kit.

Additionally, unless your crit and det upgrades are enough to increase your static's overall damage output by a generous 3-4%, you'll be hard pressed to see either of those stats outweigh the base parry rate in terms of staying alive.
