Will of the emperor seems to be bugged atm, everytime the bosses do stomp during devestating combo they are pausing before the next attack causing stacks to reset. I didnt get hit once by a combo move but still only got 4/14 op strikes. Same thing was noticed by other tank/mdps on boss. Have put bug report in to blizz but thought id let general community know anyway
Yup, absolutely bugged.. definitely related to stomp resetting stacks for me, as well. Only got 4 Opp. Strikes, got hit by 1 stomp on purpose while trying to figure out wth was going on, but 0 otherwise. Frustrating
They slowed down the arcs/stomps by a fraction of a second (not sure exactly how long, but long enough to feel it). The problem is, when he does a stomp, he has to move up to the tank (because the tank is now out of range) and this delay added to the increased move time causes your stacks to drop. If you can get your tank to move in just before the stomp goes off (or just eat it) then everyone else can gain stacks as normal. At least till its fixed.
