Other than the upgrades for Baam, shouldn't we also update Traumerei and Gustang's profiles as well, considering the final stretch of their duel? For example, Traumerei should have two keys, one for his Base and one for his Full Power, after re-absorbing all his Shinheuh. Likewise, Gustang should have a small indicator of having higher AP when using Eurasia Blossom's Flames.
So, in effect:
(Traumerei)
Tier: High 6-A, Varies, up to High 6-A with Shinheuh | At least High 6-A, higher with Evil Spirit
Key: Base | Full Power
Attack Potency: Multi-Continent level, Varies, up to Multi-Continent level with Shinheuh | At least Multi-Continent level (Immensely stronger than before after re-absorbing all of his Shinheuh. Easily annihilated Gustang's Unos, whereas neither he or Valhalla could do so before), higher with Evil Spirit (Traumerei implies it to be his most powerful Shinheuh, and it only became more powerful still after Traumerei made it absorb all the surrounding souls of the deceased, including that of Baylord Doom and Dowon's. Implied to be more powerful than Traumerei himself, who uses it to protect himself from Gustang's flames)
(Gustang)
Tier: High 6-A, higher with Eurasia Blossom's Flames
Attack Potency: Multi-Continent level, higher with Eurasia Blossom's Flames (Eurasia's power is immensely above his own. Pierced through Full Power Traumerei's Evil Spirit, and would have nearly killed him if not for Urek's intervention)
