It's fairly simple. Make all our heals proc the shield. I've been leveling a Priest and did some raiding with it, and the Holy mastery that puts a hot on people instead of a shield, works pretty good. And their AoE heal "Holy Word: Sanctuary" or Serenity, always mix them up, anyway, it heals the raid members standing in it for x every y seconds, and the mastery procs from it. This is what we need.
We need our mastery to proc from all heals. Light of Dawn, Holy Radiance. Now, Beacon of Light is a bit of a question mark in my head as I can see it being a bit over the top, but since the heal is already cut in half, it should balance itself fairly well.
The extended duration is of course a no brainer, it'll help, but we still need it to proc off of our AoE heals. The whole 1.25% > 1.5% change can be reverted in my eyes, if the above change gets implemented.
Thoughts?
