Who should I rank 5?

TheExit27

I would like to rank 5 one of my mutants, but I’m not sure which. I tend to use them all equally. The first is at signature 120, the second is signature 20 and the last isn’t awakened at all. I don’t use suicide mastery. They are at PI 9302, 9062 and 8192

Honestly you can’t go wrong with any of them take them all up eventually. I would go Mags first then Apoc and Then Prof X
