The next PTR build will have a change for both Brewmaster Monks and Guardian Druids with the Major power on Vision of Perfection.
Brewmaster Monks have had the Major effect changed to activate 玄牛砮皂
, when it procs. It will summon it for 25/35% (rank1/rank2) of the talent's duration.
Guardian Druids have had the Major effect changed to activate 化身：乌索克的守护者
for 25/35% of the talent's duration when it procs.
The Minor/passive effect is unchanged for both specs, it will still provide cooldown reduction to 壮胆酒
This should help the Essence feel a bit more noticeable and meaningful when it activates. Try it out in the next PTR build.
