Ok, I think I have two viable options and I need to know which fits.

Light (my main team, 65k+ atk)
Mike, Tish, Tsuki, Sol. Also have Meta and Light Athena
Still missing Lugh, but that doesn't matter for this MT. Is Takeminakata a good fit to have a high dmg substitute for content I don't need Sol for or does Meta already fill that roll? No one else I really want for Light, I don't have Vishnu, Frey, or SSArty but I don't think they are that great unless I am missing something?

Thunder (Secondary team, 59k+ atk)
BaalU, Thunder Aphro, Brahama, Mammon, Tyr, Thor, Marduk, Jupiter, Raiko
Crucially I have the 100% Thunder Eido though I don't enjoy using Thunder as much as Light. Question here is should I get the new Thunder healer as they seem really good. But is she better than Thunder Aphro? My main problem with thunder is I hate how squishy they seem and how difficult it is to use correctly. I am sure this could be fixed with "git gud" but I am not there yet.

Not sure which one will impact the overall play more. Could use some help. Thanks
