I had a lot of problems first day, wiped a few times. Cleaned up strat a bit and I find the fight very easy now, takes under 40 secs to kill em all with 1 tank + 4 DPS.

Strat is very simple, everyone pop green potion, tank pop purple. Burn down purple guy, you have ~10-15 secs before Frye is active so you can get him very low quickly. After purple guy (Hummel) is down have your tank go green potion now.

Next kill Frye, he tosses the pools on the ground and I've foudn thats really the only thing that can kill me. If lust is up use it on Frye, the faster you get him down the better. After Frye is dead burn down last guy, ez.

If your team does end up standing in a purple pool of course strafe out of it, but its really hard to tell sometimes. I've tried doing things like standing on fountains, tables, boxes, big machines, etc but found it more hassle than its worth.

I go in with all caster team, I took my rogue in once but he pretty much died and made the fight a lot harder. For now I'm just letting him go solo in pugs, its ridiculously easy playing solo.
