Managing 20 glimmers sounds like the kind of micromanaging chore you are complaining about turned up to 11, though. Much less of a chore than hitting a measly 5 holy power. I didn’t like Glimmer when it was like that. Using it for the damage and watching HPal pump 40k dps…that was awesome. Admittedly, I don’t spend a lot of time in raid.
You’re obviously a good player, that’s not in question. You don’t need to show me your logs.
There’s almost always someone you can WoG, however, which can also activate awakening. So you don’t even need to ‘waste’ HP in LoD 100% of the time.
I think an objective issue is that Crusader Strike costs too much mana, Flash of Light costs too much mana outside of Infusion of Light, and we need a true HP damage spender–my favorite idea being that we get the return of a divine storm that also healed for a little bit whatever allies it touched.
