Been messing with my DK playing Frost with the Amirdrassil 4-piece bonus, and I’m noticing that I don’t always get the 5 stacks of the set bonus buff because Chill Streak is fizzling. This seems to occur if the bounce chooses a target that then dies or becomes untargetable before the projectile hits. Examples include: Tindral roots, Fyrakk spirits, Fyrakk finishing his Incarnate casts throughout his fight.
One could say work around it by not casting the ability if any of these things is about to happen, but we don’t have control over what other players are doing/bursting in other scenarios such as M+ where a trash pack add might die during a bounce. The ability and bonus are designed to be cast on cooldown and it’d be nice if the DK always got the full benefit of the bonus like they should.
