If you had the choice between
a) 10 disruption, 60 spell dmg, 2% dmg crit, 22 int
and
b) a proc for an additional ~75dps
which one would you pick for raid dps and why? (with currently 700 spell dmg, 920 int, 436 disruption and volatile magic all time)

Disruption question: all I know is that it's increasing the chance to land a spell while resis/lvl of mob are an important factor as well. But is there some kind of formula? Just want to know how exactly it works, so I can tell the importance of the additional 10 disruption.

For the first question, I would choose the proc. A rough estimate of the zonewide dps increase of the crit and spell damage is 55 dps. There's not many procs that consistently hit 75 dps, though? Or is this some combination of items?

As to the 2nd question: There's no way to calculate the effect of disruption, because spell resistability also takes into account pure magic-mitigation and level disparity, which makes it too difficult to figure out whether disruption works at all.

Hm after some more testing in todays raids the proc seemed to be more like 60ish dps instead of 75 - the 75 must have been lucky I guess, was only related to a single raidparse in a t2 zone... which makes the decision even harder now ^^ Well another plus for the non-proc item would be the additional crit - which affects my other 6 dmg proc items - along with the disruption.

Hard decision still...

Oh and yes it's one single item slot I'm comparing - the bone clasped girdle vs death bringers cord with adornment.

Disruption: well of course these things would be way too hard to tell, but I just wonder if there are some general rules which I don't know. What I would like to know most is how to evaluate it... Like if I should take the numbers as they are (like 436 disruption in my case, where 10 disruption would make a difference of ~2.3% to before)... or if it might increases its effectivity at a specific point... or if its even on a curve :0 I seriously don't know anything about disruption other than the general knowledge that it relays on the mobs level and resis...

Check your parses for your spell hit rate.. If it's already up there, I wouldnt worry about the disruption. If its not, try the disruption out, see if they hit more, and if they do, then decide which is more worthwhile
