considering she also generates burst quite well, wouldn't that give thanatos more weight?
could easily say that for wind enemy content (which is why i suggested Ama and Mars cause they do more than just debuff). not sure about other content though.
but on that note buffers that come in different frames would be ideal, cause they're also an easy ticket to high damage for a few turns at the very least. going by personal experience, 160% elemental attack and 80% assault still generates over 50k per hit for a few turns with a team of Arthur (flat atk buff), Svarog (stack atk buff), Yama (elem atk buff), and Dakki (rampaging). remove the rampaging part and replace it with PF and that's still a high amount of burst damage. toss in def debuffs and this only grows in damage
