Lol, sorry I forget what the path is called. Only attempted it once. We got to the Lovers area, where you have to defend the crystals. We downed the first two or three burrows very quickly -- we had a mes throwing down the group Quickness -- and I can kite adds until the Rapture, but it seemed like teammates eventually got overwhelmed and I couldn't kill them quickly enough myself to save the last crystal.
We tried a couple of ways. 1) We split people up, two on each side to kill the burrows, once person to try to piss off the mobs and keep them busy/off the crystals. Again, I can drop AoE's and survive all day, but regardless a few mobs remained steadfastly uninterested in me and either killed teammates or killed the crystals despite me unloading on them. 2) We said screw one crystal and just tried to protect the crystal first, take down burrows as we could. We got one crystal 80% full on one try, but that's as close as we got.
Is the issue simply, "add moar DPS?" We did have a couple of lower-level characters in there, which could affect the rate of downing the burrows. Anyways, be curious to hear what you guys think.
