One of the 5.3 changes with monks was that Chi Wave, instead of healing pets or other targets that weren’t raid members, it became a “smart heal”. In the Icy Veins dev interview, someone questioned whether seeing a glyphed Chi Wave option was possible, in order to get more control.
We fixed this for 5.3. Chi Wave now does “smart healing,” so it will prioritize injured players over pets. It can still be wasted on the wrong target, but it’s hard to predict which target players consider the right one to be. Overall, it’s still a really dominant talent and not in imminent danger of not being taken. Making it too easy to use might make the other talents even less attractive.
