Yep. We use a semi-circle of ranged DPS spaced 10 yards apart; that seems to be the distance required to guarantee that even a wandering puker won't hit anyone else. Then the ranged player with the spore just runs to the middle of the line for a quick clump.

We use the W formation. The healer with the least amount of healing while movement capability goes in the centre forward position and all the ranged move to him/her during the spores.

Also try to split the raid evenly. 5 standing in melee range (2 tanks, 1 healer and extra ranged if less melee are available) and 5 in the ranged formation. Should ensure that the spores spawn separately (1 in range 1 in melee).

Yeah, first time I saw this was on 10 man and we had all the ranged and healers standing on top of each other. Everything was going fine until someone got vile gas and we died in about 5 seconds all at once. It was sort of funny actually. But yeah, won't be doing that again.

There is a minimum number of people who must be outside melee range for melee not to get vile gas.

My guild will stack everyone on the boss except for this minimum number. It keeps things tight and easy to deal with spores.

On 10 man, you must have at least 3 people outside melee range, and on 25 man you need at least 7-8 outside. The smaller numbers make it easier to spread out to avoid puking on other raid members.

Note: if anyone in the outer ring dies using this strat, someone from the inside MUST run out, or the melee will get vile gas and the raid will wipe almost instantaneously.

We do similar. We have the ranged in a W type pattern all spread out and clump the spore where we place the totems in front of the door. As far as I have been able to find out the range of the spore is 5 yards. So, if you range with a zig zag pattern all 10 yards apart, you should only have to move 5 or 10 yards max to get the buff. There is a pretty steep DPS requirement for this fight, so the less movement the better.
