Yorsahj Ooze Priorities

When my guild ran through Dragonsoul last week, our warlock--known to us as Bob even though it's neither his name nor his character's name (mostly because we didn't feel like calling him Damorons, and it stuck even after he changed his character name)--had spent a lot of time on the PTR and had put together a quick guide for us on each boss. He then, essentially, lead the raid as we went through, as the one with experience on it.

Out of all the bosses, the one that truly baffled me even after having downed it was Yorsajh. Oozes, oozes everywhere, all colorful and complicated! AHHHH!

When I went and ran three LFR raids following our normal raid, I tried to get a better grasp of what those oozes do and their priorities, but it was still a bit of a foreign concept to me that I was struggling to comprehend. So, when we started talking heroic modes and that we'd be seeing FOUR at once (3 simultaneous buffs), and I was already feeling a flowchart was needed, I sat down in google docs and made one.

This involved a ton of research and comparison of comments and suggestions. Here are some places I studied:

• Icy Veins' guide
  
• Sumanhi's slightly different version of Icy Veins' guide (had more details on alternative combinations and strats to deal with them)
  
• Wowhead, mostly via the comments due to limited strat details on main page
  
• Wowpedia

(I saw Beru posted something too, using one of the priorities, but didn't get a chance to read that in detail because I was doing resto shammy research at the time. Will edit this with hers as well. As a side tangent, my shaman alt went resto for the first time ever yesterday, and... well, it's a work in progress :) )

So. Multiple suggestions on ooze priorities. Icy Veins even appears to have altered their original to reflect a different priority. And, it seems, no hint of what combinations to expect on heroic mode.

That said, here are the results of my search:

LFR
There are two different recommendations on ooze priorities here.

• Y > P > Black
  This priority avoids the combination of blue/yellow, instead resulting in a blue/purple. What this means is that the dps kills the void while there is little raid damage going out, and healers shouldn't need to be healing much. However, the healers need to understand not to spam fast heals on the tank during this phase; a single, slow-cast healer should be adequate.
• P > Y > Black
  This priority is for when you just don't want to risk the healers exploding everyone. In the case of Blue/Yellow, things will get nasty and your tanks need to swap quickly as their debuffs will build fast from the yellow buff, and healers will be OoM or low mana. Risk is loosing a tank.

Normal
Normal mode makes green pretty scary. You will want to get rid of it. Again, there are two different suggested priority systems here.

• G > Y > P
  This avoids a blue/yellow and a blue/green scenario, replacing both with a blue/purple scenario where, although the healers need to not be casting 5 heals on any one player, there is little damage going out. The healers need to understand not to spam fast heals on the tank during this phase; a single, slow-cast healer should be adequate.
• P > G > Y
  This completely removes purple (shadow) from the equation, but will have higher healing requirements due to the blue/yellow and blue/green situations.

Heroic
Where in normal and LFR it appears that there are only six possible combinations that will spawn together, I haven't found a list of possible combinations for heroic mode's spawns to be able to analyze the priority system. A tentatively suggested system is P > G > Y > Black > Red. Any further information on this would be very much appreciated :)

EDIT: Heroic version
