There are about a billion examples of this in my macros on the first page...Elemental/Enhancement Shaman Flame Shock....Enhancement Stormstrike....Both Warlock specs for their dots... Also checking buffs and debuffs is essentially the same so you can also model off of Beacon of Light, Earth Shield, Sacred Shield, etc, etc, etc.
- Who still does ToC anyway? O_o
- Why is some noob getting hit so Icehowl enrages?
If you want something to dispel, make a special macro to detect Vampiric Might on a Cult Fanatic for the Lady Deathwhisper fight...there's something worth dispelling nowadays.
To be honest though....in general I feel Tranq Shot is only really used in raiding for enrage effects....and even then only if you don't have a rogue handling it...you should probably just hit the button yourself... You've already got basically everything else on one button...what's the harm in a second? =p
