I have only just got round to play frost spec since legion and have noticed that almost everytime I use BoS it stops within seconds despite having more than enough tunic power to keep it going. Has this been an on going bug for a while?
I literally feel like I have to play obliteration because I can never get more than 1 second on BoS.
Would be interesting to hear if anyone else experiences this.
I have the same issue sometimes,it seem to stop earlier when you get below the required amount,even if you have some time before the tick,but not always,could be your problem here?
It is likely just the infamous double tap, if they would put a 2 second delay before you are allowed to stop the breath then this issue would be fixed overnight.
