Justice’s main role is to be a tank. Telluria is a better tank than her so I wouldn’t give the darts to Justice.
The best position for JF is on flank. He should fire earlier in the battle in order to make a difference.
I’d try to replace Neith with someone else and run Seshat-Misandra-Telluria-JF-(Joon/Poseidon?).
You can also try to replace Misandra if you have a better blue.
If you have to run the current team, I’d change it to Seshat-JF-Telluria-Neith-Misandra (the problem here is that IF Misandra chains and IF she adds enough mana to her allies that their mana bar becomes full, they won’t be able to fire in the same turn. Even though this is too hypotetical, this positioning isn’t ideal).
