Return of Reckoning

Hi guys,
I receive a yellow message recently like below:
After that i asked this to friends online and Krunched told me to talk to Mickeyrooney(sorry if misspelled). He asked me to write this to bugtracker but unfortunately i cannot get a new account,whatever i write it says that name or mail address is already taken. So just to inform you i am dropping this here.
Except than this ss i got today 480% also at RVR in one swing 3 times at the same time(2nd was 390% and 3rd was 450% consecutively).
Tactics i am using are:
Brute Force
Wild Gambit
Slaughter
Fierce Might

I am thinking about maybe with fierce might and bersek mode of Slayer is conflicting.

Anyways hope this is helpful. I will be offline for 4 days,gotta catch a flight now.

For your considiration, keep up the good work.

Fierce Might is causing it, especially when you drop below 10%/are dead

i once had been crit from 800 from a slayer snare.......

It's already on bugtracker.
