Heroic Yor'sahj Healing

[Medlin]

This is a comprehensive list that I have compiled for healing during Deep Corruption in Heroic Mode Yor'sahj the Unsleeping, when the boss absorbs a Shadowed Globule. It seemed easier to compile this information rather than add it piecemeal to previous posts. It is organized by class (healing classes first), and each class section lists abilities giving NO stacks first, then 1 or more stacks; raid wipers are listed at the end of each section!

Keep in mind that all direct heals will add 1 stack of Deep Corruption. Direct heals are not listed below for that reason.

Deep Corruption lasts 25 seconds in Heroic Mode, and after those 25 seconds is reset and refreshed. This results in a total of two 25-second debuffs per phase where Shadowed Globule is absorbed. Adding stacks WILL NOT extend the timer; therefore if someone has 3 stacks with 5 seconds left (for example), those stacks will be wiped clean after 5 seconds even if he/she receives more heals before the debuff expires.

ooooommmmfffff that is hella hard for healers. People will have to be very watchful of where they are at what they are doing, mitigating every bit of damage possible, have the health stone at ready as well as a healing pot and maxed band-aids, those can really help in a pinch if people can use them and remember to use them when possible. Five seconds minute not seem that long but healers are almost always required to pump out heals and might not be able to heal you because of the stacks.

Even though I'm not there I know you guys can do it.
