if you could take any hero and add a * to them (essentially giving them another round of leveling to get comparable stats) who would it be?
thoughts so far for me lead to Brienne and Ulmer. briennes power is awesome since it stacks with other attack boosters. having her at 4* or 5* would be awesome. Ulmer has such a high attack stat for a 3* that i think he would be a beast if raised to 4 or 5*.
kailani (or gunner) would be nice too. the damage mitigation they provide would be awesome at 5*
