If he still needs to use other Sin Cards, he barely has enough Mana Points left for healing.
If the team needs healing, Aiwass would have to transform into the Sin Beast. By devouring the Sin Thorns to urgently restore Mana, he could meet the needs of healing the team members — and if he does so, he won't be able to use Lost Paradise to perform a burst attack. Because the wings can only be summoned in human form.
Moreover, even if he can regenerate Mana, his Mana must be prioritized for damage output... there's hardly enough left for healing. If he focuses on healing, then there won't be enough damage output.
— A total of four melee fighters, with only half a healer and half a shield. The only proper ranged damage dealers are Zhu Tang and Aiwass, and it's unclear if Zhu Tang can break through defenses. The other ranged characters are all crowd control PvP players — naturally, they can't control the Fallen Celestial Marshal.
It's a somewhat desperate team.
