Currently using Darkmoon Card:Greatness and Mirror of Truth. Wondering if it's worth dropping the Mirror for Fury of the Five Flights. Thanks.
You're looking at 320AP passive on the Fury (when fully stacked) vs. 84 crit rating and the 1000AP proc on the Mirror. There's not a lot of info (at least that quickly available) about the proc on the Mirror - some debate at whether it might be 1ppm. If that's the case it would average out at 167AP over a minute. It might depend on your other stats a bit, but I'm guessing that Fury of the Five Flights is likely to give a better result, unless its a fight that involves movement or there's any danger of the stack falling off.
