Tell me one reason not to R4 Megasonic Mutant
I'm having her R3 and having other mutants as well like, onslaught, cyclops, mrsinster, gentle, bishop, domino..
But I feel her, seems to be perfect option for R4 as she can easily defeat most annoying champs like Bullseye, korg, attuma, nick fury etc...
But few challenges with yelena alone, but doable...
So what I'm missing and what's your suggestion as not to R4 and go for better Mutant offence...
