meh. If I was rerolling I'd try for a +spd Summer Corrin as ranged fliers are extremely rare, she's literally the second one ever and both are limited. Then I'd use all my story orbs on Hero Fest next week for a Julia and Ninian. Julia is a hard counter for Reinhardt who is an omnipresent arena threat atm and dancers are always extremely useful.
I mean, a double 5* roll is a rare occasion and I guess after months of playing I have almost forgotten what it's like not to have a 5* at all. Those two easily clear most of what you'll be doing for the first few weeks (story, low point arena). I never rerolled at all and it worked out in the end, they give out so much stuff in this game. Just saying what I'd do in your place with what I know now.
