With the short raid weeks we've had do to the holidays, we decided to knock out some of the achievements. One of the easiest ones to accomplish is Flu Shot Shortage. With the normal Festergut encounter, we usually setup 7 ranged, with one or two collapse points. Ranged DPS keep up range finders for 8 yards – to prevent a chain vomiting from Vile Gas. Any extra ranged that benefit the most from stationary positions are setup within the melee and healers. If we are short on ranged DPS, we will move a healer out with the ranged DPS. There is some randomness to this – provided that the tank doesn't get one of the first spores, or that the same person doesn't get spores three times in a row.
Otherwise, if needed, you can adjust the ideas to what is actually occurring in your raid environment – provided your raiders have solid reaction time. Make sure all of your raiders are sitting above 20k health and have health stones and healing potions. Vile Gas recipients need to be healed up as quickly as possible. Also make sure you have Shadow Protection up- and a paladin spec'd into Aura Mastery can help save someone who only manages to get one stack of inoculation.
First Spore Spawn- all raiders with a spore move away from your collapse positions. The rest of the raid continues to collapse and respond as if the fight was continuing normally.
Second Spore Spawn – the people that previously had the spores run out. The current people with the spores run in to their perspective collapse points. At this point, the entire raid should have 1 stack of inoculation. If for any reason, you have someone with two stacks at this point, that person will have to move away from his/her group on the next spore.
On the third spore, you treat it as normal- and everyone collapses. Pungent Blight will hit for quite a bit of damage but you should be able to heal through it easily.
Hopefully, this will help you get the achievement for raid guild. Good Luck!
