Now that Faceted Foes are spawning in the Night Market, and instance populations seem to be up (yay!), just a reminder: if you don't have a group tank, pulling 3 Faceted Foes at once (plus their associated mobs) will just keep wiping your group. Honestly, even if you do have a tank, if group DPS is low, 3 Faceted at once will be VERY challenging.
Tonight, I watched several groups pull multiple Faceted Foes at once, continuously wipe for 10-15 minutes, and never try a smaller pull. I try to help out while I"m doing my quests, but if your group won't even lower pull size when it's clear the group can't handle the bigger pull... your group isn't getting far.
Sorry if this sounds harsh, but it's said to help groups improve. There's nothing "bad" about pulling FEWER things, if it's what your group can successfully handle.
