Don't be writing off Titania. After awakening every 4 turns she gets 45 burst gauge, gives one ally 30 burst gauge and gives another ally 50% double attack / 50% triple attack for 3 turns (so another 45 burst gauge for them). You will be a bursting machine with her. And the extra combo attacks, 60% att, and 75% ability damage from her buffs will add truckloads of damage also. She is Wind's secret firepower trump card.
