Primarily a lurker and new to Boomer in WoD, so don't kill me.
I've noticed a lot of people who are talking about Celestial Alignment unglyphed, and this seems strange to me as I'd imagined no-one would use it unglyphed.
Reasoning:
* Unglyphed CA is 15 seconds. During this 15s you can cast at most 10 instant cast spells on GCD.
* To get the most out of CA you're casting empowered Starfire's. A reasonable use of:
0.0s: Moonfire(+Sunfire) +1.5s
1.5s: Starsurge +1.5s
3.0s: Starfire +2.5s
5.5s: Starfire +2.5s
8.0s: Starsurge +1.5s
9.5s: Starfire +2.5s
11.0s: Starfire +2.5s
13.5s: Starsurge +1.5s
15.0s: CA fades.
With massive haste/Berserk/HeroLust you're at best going to get 2 more casts out, when the Starfires cap at 1.5s.
So without using it during exactly the right conditions, the glyph doesn't reduce the number of actions you can perform during the CA. What the glyph does give you is a massive boost to movement capability, because you don't have to have 15s of uninterrupted casting to still get the same damage output.
Additionally, if you're going heavy on Starfall, you can actually have the Lunar maximum effect applied to it for longer than 15s simply by not casting the last spell for a bit (up to a minute, but that's probably going to lose DPS after a bit).
So, my question is: What's the benefit of using CA unglyphed ever?
