I get why you did it, but even in circumstances such as this we prefer that you not cross-post stuff. Thanks.
It has been mentioned previously in this thread, but as I just posted this in the combat thread, I thought I should post it here as it's directly related to shadowcraft:
Kiroptyric Sigil appears to be calculating its EP value as if it had a 60 second cooldown rather than the 90 second cooldown it actually has. By my calculations, this should be worth 1829.71 EP for my rogue. However, shadowcraft shows it as worth around 2330. When I changed the CD to 60 seconds, I ended up with an EP value of 2336 for Sigil.
