Is it possible to do something like:
Molag Kena
Elegance front bar
Undaunted Weaver back bar
Switch to back bar to cast wall of elements to get the enemy off balance and activate the undaunted weaver bonus. Then switch to front bar, LA x2 for Molag Kena proc and then spam HA. Repeat every 8s.
Cast DoTs/buffs/debuffs where appropriate etc.
