Just a heads-up about a bug we discovered last night. Using LL on a target with FS while it has enemies nearby was bringing down the damage of the LL on that target.
Specifically we were testing by my very well geared enhance hitting a full PvE resto shammy as a test dummy, and noticed my LL ranged between 7k crits (wtf?!) and 90k crits (yes please) depending on FS being up or not, and furthermore depending on how many critters/neutral piggies (we were in the pig pen outside Org) were nearby.
Will run more thorough testing later and possibly put up a bug report. Just never noticed this one before, but I can't say how old it is. Please check it out and comment.
