Just attempted this leve today, was completely unable to finish it and had to abandon it. Lost 1k+ marks on it.
Basically though the quest sent me to the room with Bardi and multiple fire elementals and yarzons (3,5 I think). Even tried getting on a higher class and clearing the room aside from Bardi but the room is too small. Hopefully the mob readjustments will take care of this, if not please take this into consideration SE.
