Welcome back to everyone’s favorite(ish) Q&A with one sexy rogue (that’s me by the way). Been a busy week, what with all the 3.1 PTR craziness and excitement but I haven’t forgotten you, my loyal readers so here you are. This one gets a little mathy…everyone likes math right?

*Hey. I’ve been reading you blog for a few weeks now and your macros have been exceptionally helpful as was the nifty wound vs instant poison chart *

*I was browsing your armory and I saw you also use “Signet of Edward the Odd” on a pure stat for stat basis its inferior to most rings because I have no way to calculate the DPS of the haste proc. What have you found for a proc rate so far or some numbers on it?*

Ah, the Signet of Edward the Odd. Who exactly is that guy actually? And why does he like haste so much? So, yes, I am using the signet and it is a fairly solid ring though far from the best one could acquire. According to wowhead, it has a proc rate of 15% and it does have an internal cooldown of 45 seconds. I used the following formula to calculate the proc uptime (source), someone correct me if I’m wrong here.

D = Duration of the buff

P = Chance the buff procs on any given attack

V = Number of attacks that can trigger the proc in a given second

c = Internal cooldown of the proc

u = uptime

A = speed one

B = speed two

V = AB/(A+B)

Plugging in my weapon speeds we get:

u = 13/(45+6.3)

u = 14/51.1

u = 25.4%

So, you’re looking at a 25.4% uptime. So, 125 haste, 25.4% of the time makes this trinket worth about 31.25 haste.

Keep in mind that this is napkin math and it doesn’t take into account procs from your special attacks but I think it’s pretty close. I also left my weapon speeds at their starting values rather that calculating in my current haste rating.

Conclusion or TL;DR: While a good ring, I wouldn’t pay anything absurd for it on the AH (I got mine though a random drop). If you happen to have one, play around with it. Plug it into a spreadsheet and spend some time on the training dummies to see if it works for you.

I hope that answers your question.

If anyone else as a question, leave a comment below or drop me a line.

Remember, follow your heart and stab your enemy in theirs.

Thank you very much Zaltu! This has been most insightful. Sadly I bought the ring off the AH early on in Wotlk and now am finding upgrades. Thanks regardless,

Eresin’s last blog post..Been Tagged again!@eresin

I’m not sure how I could prove it anymore than just continuing to be my awesome self

The expression V = AB/(A+B) is the number of seconds per attack. So the description “Number of attacks that can trigger the proc in a given second” confused me, since that implies attacks per second (the inverse of what it actually is). Including the units in your calculation is always a good idea, e.g. (seconds/attack) / (procs/attack) = seconds/proc

Your formula seems correct, but .95/.15 = 6.33, not 1.1. And the 13 inexplicably changed into 14 in the 2nd-last line. Without those errors you would get 25% uptime. You might also consider haste (divide V by hastefromgear * SnD). But I couldn’t figure out how you got V=.95 either.

@R

Good catch on those, that’s why it’s called napkin math after all. I’m made the corrections.
