Now, this is more for whomever your healing, or yourself if you need to.
As we all know, Lifebloom, when dispelled heals for a full amount of 600, but in private servers, it can "bloom" up to 3 times, once per stack. Here's where the exploit is, If you need spike healing, Make a macro (Call it what you will) with two simple lines.
/cast Lifebloom
/cancelaura Lifebloom
This causes the lifebloom to pop as soon as you use it on yourself, and heal for the "dispelling" amount of 600. Great spike healing if you can't wait for the 6 seconds to finish.
(I wouldn't believe seeing this as common sense, seeing as it isn't being dispelled, But I'll let you all be the judges of that.) Thank you for your time and if you see something along these lines, I'm sorry, I'll delete the thread immediately. Discovered this on WoWscape =D.
