I did some searching, hoping to find where anyone has actually measured LFR loot stastics with a decent sample size (besides someone complaining they've gotten nothing in 45 kills or whathaveyou) and come up empty.
I know we have some dataheads here, so I figured I might find some other folks who have been keeping track of their luck in lfr. With enough people, we could get enough data to make some reasonable conclusions.
Here's my stats to kick things off:
175 bosses killed
14 items dropped
20 coins spent
3 bonus items awarded
