What's up bros. Video about this bug.
Warrior from the video.
TL DR: In short HS makes BB to deal less damage if it hits at the same time as BB tick.

Total BB damage should be: Slam 87365 (30%=26209) Heroic Strike 30000 (30%=9000) 26209+9000=35209Right? But it's not equal to the damage we have!
(Slam)4367+4367+4367+(Heroic Strike)+2533+2533+2533+2533+2533+2533+2533=30832
BB lacks 4377 damage! 4377 damage....wait a minute, this is our 4th BB tick after the Slam!!!! (10 more dmg = 1 dmg for each BB tick, because it's a dummy)
But how did we lost this tick? What stopped it from hitting the dummy? Heroic strike. It looks like that HS prevents BB ticks from hitting the target if HS hits at the same time as bb tick. (wotlk hs bug anyone?)
What do you guys think about this? Guess we should send this to Blizzard.
