5 star questing team rank up help

Bigg_Dogg

Medusa and hood are both rank 4. I have resources to add another rank 4 5star. Strictly for questing (act5 100%). My choices are x23, korg, sabretooth and Hawkeye. Who would help most??

Tough call. Since you've said "questing" specifically, X-23 is gonna be really valuable. She has good damage and is the most sustainable out of all of the other options. She will save you a boat load of potions and revives.
