Reroll Priority

Who to Reroll for

PLEASE Take all lists with a grain of salt. Don't follow brainlessly as all students have an use somewhere.

Strikethrough means not in pool atm. Will be subjected to change as time goes.

Hina and Aru as they are the best explosion DPS, helps u melt through story quickly. Tsurugi will be core for several future raids (from CBT)

You can also refer to Hespa's student tier/analysis doc. I agree with most, if not all of what's there.
