Not much insight really, it was pretty easy to see spores, and, personally, I found it not all that difficult to stack the innoculated debuff (buff?).

I wonder if it might be helpful to have more preset locations where we stand, at times I was running into melee to follow a spore-d person and there were no other spores around. Although it might take a little longer to get started with dps, I'm guessing that more thoroughly dispersing around the room would be most beneficial for the fight--we had a large clump of ranged / heals close to the door.

Of course, that's just one pull, and it could all change if / when people become more familiar with the fight.
