I respecced from the traditional 49/12 last week for some testing of Seal of the Crusader. I dropped some points in defense rating and moved them to the Improved Talent. The debuff adds 3% spell and melee critical chance to any raid member attacking that target. Here is some of the math I was working out.
Looking through a WWS of Teron Gorefiend about a month ago, the top DPS classes hovered anywhere from 1000-1300 DPS on average. If you crit at 200% critical damage (or something close to that, +190% Ignite, +180% Mortal Shots whatever) then you could expect a 36 DPS increase assuming an average output of 1200 DPS.
36 DPS increase over 16 dealers means the raid gained 576 DPS from the 3% crit Judgement alone. Obviously not every damage class does 1200 DPS on Teron Gorefiend, but even if you were to round down significantly a gain of 400+ raidwide DPS would be realized. This seems pretty significant to me, and it provides me some extra raid utility when I'm not tanking something.
Going from one week without the judgement to a week with it, the top 5 DPS on Teron Gorefiend looks like this.
As you can see the first raid's top 5 did 8897 collective DPS, averaging 1779 DPS a piece. Adding Seal of the Crusader, the top 5 produced 9474 DPS, averaging 1894 DPS. Now obviously a lot of factors come into play when looking at top DPS. Were the targets threat capped? Did they consumable this week and not the last? Obviously more parses with and without the judgement would be needed, but the fact that 3 of the top 5 were the same from week to week adds legitimacy to the debuff slot. More on this later.
