Old man Logan > Domino. Change my mind
OML is almost completely forgotten about nowadays, that's not cool. Ever since his shared buff, Colossus took to the spotlight, and everybody neglected old man Logan. Since Domino is now that apparent standard of comparison among mutants, here's why I think he's better:
Guaranteed armor breaks; AAR immunity; bleed resistance that's more powerful than Omega red's; rocks suicides almost as well as corvus, healing from the bleed like willpower; he's got bleeds, crit bleeds, guaranteed furies (buffed up counter); can work for energy adoption: (lightning? The one that armor break stops); his bleeds when purified, cause an auxiliary amount of damage to the opponent, making him usable for tenacity lanes.
In addition, there's his non-reliance on synergies. Anything I missed?
As for the RNG queen herself, she most definitely doesn't have as much going for her as OML does, imo.
