She doesnt actually have more fimess.
Vulcan in this comic is a shell of his former self. He's full on delusional even. He's been creating emergy constructs of his dead friends and is completely convinced their real.
He was essentially experimented on by elders of the void, and this has lead to an extre cap on his powers and a state of being mentally unwell.
So the fight had nothing to do with storm having more finess. She was just fighting vulcan at his worst
