Думаю ГМам стоит пофиксить, как и большинство трынкетов не имеющих internal cooldown.
45 second internal cooldown.
Can proc on most direct heals including:
Chain heal hits
CoH hits
PoM hits
As Tapioka pointed out, it can only proc once between cooldowns.
Expect a healing increase of 1-3% in a mix of 200-213 gear.
