For all testing, only your addon was installed. This is a clean beta install with no other 3rd party addons having been installed prior to testing.
PriestDiscipline:
ArchangelWhen talented in both
Evangelism and
Archangel, casting
Smite 5 times will stack Evangelism to a 5 stack (capped) which then creates a glow border around Archangel in the tool bar. Using the macro:
#showtooltip Archangel
/cast Archangel
Observations: The macro in the action bar does not get a glow border with a 5 stack of Evangelism. Additionally, when Smite is cast at least one time and procs Evangelism, the Archangel icon goes from dark or shaded (not usable) to lit up (usable) on the action bar. This "light up when usable" doesn't work with an Archangel macro as well.
Holy: Currently there are no Holy spells which gain the "glowy border". However, Holy priests *can* spec into Evangelism/Archangel in the Disc tree (not that they would).
Shadow:
Archangel (Dark Archangel)When talented in both
Evangelism and
Archangel in the disc tree, casting Mind Flay repeatedly will stack
Dark Evangelism to a 5 stack (capped) which then creates a glow border around Archangel in the tool bar. Using your mod and a macro:
#showtooltip Archangel
/cast Archangel
Observations: The macro in the action bar does not get a glow border with a 5 stack of Dark Evangelism. Additionally, when Mind Flay is cast at least one time and procs one stack of Dark Evangelism, the Archangel icon goes from dark or shaded (not usable) to lit up (usable) on the action bar. This "light up when usable" doesn't work with an Archangel macro as well. Also, there is no "Dark Archangel" Icon, the Archangel spell gets the "glowy border" and when cast, you gain the Dark Archangel buff.
Mind Blast and
Mind SpikeWhen
Shadow Orbs are proc'd from a chance from damage dealt by
Shadow Word: Pain and
Mind Flay. When this reaches a 3 stack of Shadow Orbs (cap), then
Mind Blast and
Mind Spike gain the "glowy border" effect. Using the macro:
#showtooltip Mind Blast
/cast Mind Blast
and
#showtooltip Mind Spike
/cast Mind spike
Observations: When using both macros, both never gained the "glowing border" effect after a 3 stack of Shadow Orbs.
Additional info on priest spec:
Mind Spike when cast actually stacks a buff of its own called Mind Spike which stacks 3 times. This buff increases the critical strike of your next Mind Blast. When Mind Spike is at a 3 stack, Mind Blast *doesn't* gain a "glowing border". My guess is that if this buff stack were to cap and proc the glowing effect, it would confuse the player that they had a full stack of Dark Evangelism and not a full stack of Mind Spike.
Also, I think when the
Glyph of Shadow Word: Death is equipped, it would be pretty nice if
Shadow Word: Death could gain the "glowy border" if just once, to instantly let the player know their current target is below 25%. I'm sure other addons could give warnings like that, but might be kind of nice to include that ability.
