Tobypine2

I'd like a little advice. I'd gone maybe 4 chapters into the story and then thought maybe I should reroll. So I did and out of the first and only 5 summons got, Setsuna, Peri, Stahl and Eliwood. All 4*. Should that suffice, or is it better to start again and roll til i get a 5* even if the others are 3s?
