Let's bring some actual numbers to it.

Let's assume the following stats, taken from

Rizzy (highest rated non-human rogue I found).

33798 AP

16760 Agility

54,2% Mastery

51.87% PvP Power

Thugcleave is the comp and we have Stampede, so pretty much every buff in the game is active.

10% AP, 5% agility, 3000 mastery

Let's also assume that Synpase Springs, Dancing Steel and the PvP Proc trinket is active. As well as Prey on the Weak, Master of Subtlety and Find Weakness.

As target I'll take

Mädmäx (Shaman with the highest resilience I found in a short term).

The stats now turn into:

27868 Agility

56017 Attack Power (60531 with Blood Fury)

69,2% Mastery

51,87% PvP Power

The target has 41916 armor before Find Weakness and 10458 Resilience rating.

The Eviscerate formula is for maximum damage is:

=(6009+0.8*AP)*(1+PvP Power Percentage)*(1+Mastery Percentage)*2,03 (Crit damage)

With the current stats Eviscerate crits for 265112 damage on a target with 0 armor and 0 resilience.

Now we have the modifiers and the target to factor in:

265111 * 1,1 (MoS) * 1,1 (Prey on the Weak) = 320785 damage

Armor: 41916 - (0,7*41916) = 12575 armor, which is about 21,4% damage reduction.

320785 - (0,214*320785) = 252137 damage

Resilience: 68,28%: 252137 - (0,683 * 252137) = 79927 crit damage - ok, there seems to be an error
