In our group the bard grabs the blue puddle and gets every red fire. We've been beating it for 7 weeks now and it hasn't wiped us except for when we were learning. It's not much at all for one person to handle. There are plenty of mechanics in this coil where one person generally takes care of it. Especially on the healer side. I see no reason to avoid doing it here when we already have to do similar roles elsewhere.
