list of friendly macros I have developed and discovered to help get me through Ulduar Hard mode. I play a Shadow/Disc priest, so keep in mind Some of these macros are spec and class specific. I almost always bind them to my 1 key and that way I always have access, and I change them for every fight.
Flame Leviathan
Useful as a demolisher passanger to keep your pyrite stocked fully./tar liquid pyrite
/use grab crate
/cast grab crate
/targetlasttarget
Ignis the Furnace Master
Helpful for tanks that struggle with finding the Iron cunstructs during this encounter./tar Iron Construct
/cast Taunt, Growl, whatever pallys do
Razorscale
Self explanitory, but there was a short while where some of the folks in my raid had a tuff time differentiating between a Dwarf, and a Vrykul.. Go figure. This macro saved the day./tar Sentinal
XT-002 Deconstructor
Self explanitory, helps you get a jump on heart DPS./tar Heart of the Deconstructor
Specific to Hardmode, feel free to sub in whatever spells or spells you need to get that spark down ASAP./tar Life Spark
/cast Shadow Word: Pain
/targetlasttarget
Great for helping out whenever possible. Will not de-target XT. Is great for meter padding as well :P/tar XM-024
/cast Shadow Word: Pain
/targetlasttarget
Iron Council
Rune punch safty macro.. If you can Dispel, regardless of your class/spec. you SHOULD absolutly be spamming this when you see "RUNE PUNCH" on your tank. Your letting your crew down if your not./tar Maintanks name
/cast dispel Magic
/targetlasttarget
Freya
When trying to hardmode it is imperative that "everyone" works on both gift/roots to maximize efficientcy./tar Eonar's Gift
/tar Strengthened Iron Roots
/cast Mind Flay
/targetlasttarget (replace with whatever spell you need)
Thorim
As a Shadowpriest I use this to target a Dark Rune Warbringer at the end of the arena phase. Then I use this macro to MC it./tar Dark Rune Warbringer
This macro Alows me to [ALT-click] and have the target set as Focus. Then I can target whatever I want and all I have to do is press it again, and it will auto MC the first target that I [ALT-Clicked]#showtooltip
/clearfocus
[modifier:alt][target=focus,dead][target=focus,help][target=focus,noexists]
/focus [target=focus,noexists]
/cast [target=focus] Mind Control
**Note** If you want to MC in this fight you need frost res gear, and make sure you are standing directly underneath Thorims balcony.
Mimiron
This Macro is for Plasma blast on Mimiron. It will immediately STOP anything you are casting, and applys Pain supression. As a Disc priest it comes in quite handy throughout the instance, as well as others. I just call it a Mimiron macro because he inspired it. Holy priest could also adapt it to fire Guardian spirit. As well as most other mitigation spells from other classes. ie:Paladins./stopcasting
/tar Maintanks name
/cast Pain Suppression
/targetlasttarget
Yogg Sarron
Cheap and easy Achievement (remember this is ONLY during P2)/tar Sara
/kiss
/targetlasttarget
General
A must have for ANY raid fight. sets the maximum distance you can pull your camera out to way beyond default settings./script SetCVar("cameraDistanceMax",30)
The speed kill for Hodir require cluth healing/DPS. I find this macro to be invaluble, and have currently replaced my normal Mass dispel key with it as the stopcast is key to being an efficient dispeller./stopcasting
/cast Mass Dispel
/targetlasttarget
