Is Sharena worth using on my team? I have a 4* Nino (+HP, -Res), 4* Olivia, a 5* Lucina (+Spd, -Def), and a 5* Robin (+Res, -Def) on my team right now, along with a 4* Sharena, a 5* Lilina (IDK about IVs, but not -Atk or -Spd), and a 4* Cordelia (+Atk, -HP). If I add Sharena, I'll probably promote her first (I'll get enough feathers after this arena's finished), while otherwise I'll promote Nino.
