I mean, if you don't have a dark weapon pool at the moment then that'll hamper your strength by a fair margin. Most of your light weapons probably have Light Atk/HP up for your light team, though 100% aura from Bahamut is too good to pass up. I'd say go Light for now until you can build up a dark weapon pool. I wouldn't put Odin on the same level as Bahamut or Lucifer, though maybe that's changed. Someone who mains light or dark could explain this better than me (scrub with Luminiera and Celeste)because i feel bad after pulling Lucio and not using him. That 800% light damage is strong af.
Is it recommended to use mixed team with odin since he boost both Light and dark at the same time.
And all my weapon pool is light or other element and someone said that it is better to use dark weapon pool for dark team (not sure what the effect is)
