I have been thinking lately about going for the full exp cap because of that. I get my information from a mix of elitest jerks, noxx, and sacred, and also I pay attention to all of the other pallies I see and base my build on what they are doing for their sets.
I spec'd into Holy Prism because it is amazingly useful on 10man when you have less adds and people so in that environment I get a better dps and healing outcome from that rather than using the hammer. In a 25man environment I can see how that hammer would do more healing/damage in general but the differences from 10/25 raid wise pushed me towards prism. The gcd gap from haste stacking is generally not a problem for the 20second cooldown, I won't fit it into my rotation while running my Holy Avenger because well, you don't have a whole lot of time to while hero is up and you are trying to get that holy power as quick as possible to keep you SotR buff up for a longer duration. The gap is actually there in a rotation where you can fit it in though on the cooldown. It takes priority at times based off the hp of the group around you and other reasons that are mostly situational.
My priority would go as follows Judgement>CS>SotR>Avengers Shield>Consencration>Holy Wrath>Holy Prism
This of course flows throughout the fight and sometimes other moves will come before their time.
I actually just got that ui set up this week because of that reason. I didn't have it Tuesday when we raided and I noticed that I was getting horrible and keeping that up. The addon has helped me a ton since I've started to use it so that shouldn't really be a problem. Playing on a 40' screen it isn't the easiest thing to look up to your right all the time to check a buff in the midst of lots of other buffs on you while in a fight so I think that's where I started to slack on that, hense why I redid my UI.
The glyphs that I typically swap throughout the night are as follows
HoF-
Viz- Divine protection glyph(20% dmg reduction from phys/mag) & focused shield because there aren't more than one add together at once.
Blade Lord- I'll keep the same glyphs from Viz for this because they both still apply
Garalon- Same ones
Wind Lord- I'll take off focused shield for this one and replace it with the 1% hp per sec while avenging wrath is up, either that or consencration for the added utility on my placements.
Amber Shaper- Ill keep the same setup as I did for Wind Lord
Shek- Same wind lord setup
MSV-
Stone Guards- Divine Protection/Avenging Wrath/Alabaster Shield
Feng- Same, though I may take out the divine prot glyph because of the damage from lightning lash and the debuffs
Gara- Divine Prot/Focused Shield/Alabaster Shield
Four Kings- Divine Prot/Avenging Wrath/Alabaster Shield
Elegon- Same as four kings
Will- Divine Prot/Focused Shield/Alabaster Shield
ToeS-
Prot- Divine Prot/Avenging Wrath/Alabaster Shield
Tsulong- Same as Prot
Lei Shi- Focused Shield/Avenging Wrath/Alabaster Shield
Sha- Focused Shield/Divine Prot/Alabaster Shield
Talens I use in raid
BASE SETUP
Speed of Light
Fist of Justice
Sacred Shield
Clemency
Holy Avenger
Holy Prism
I rarely change these around in raids, the only time I really change them is on H Will where I spec Pursuit of Justice over speed for the swings, the constant speed increase makes it a lot easier then running out of a speed increase 1/2 way through his swings.
When we were on Viz I was purely practicing, I hadn't actually done the fight yet so the first few pulls were pretty sketchy trying to figure out what I do and when, by the 3rd pull it wasn't an issue and I didn't get hit and we actually sat on his platform for a little while just letting the people who hadn't seen the fight that much practice it for this week i'm assuming. The problem isn't there right now.
