That at least I'll agree with. The "nanomachine brain/enhanced brain" argument is a terrible one- it's vague at best and not borne out in in the games at all at worst.
but here's an excuse to post more stuff about wolverine's level of fighting skill. I think it's undersold here.
Here we have wolverine in the danger room with his brain wave patterns being measured. Forge calls his combat skills "extraordinary", and analogous to an olympic gymnast performing a gold medal routine, while beating four chess computers in his head simultaneously.
Hyperbole? a one off? maybe not. Here we have him absolutely dominating Shang Chi, master of Kung Fu.
"His Savagery has not made him undisciplined. his focus and control rivals the samurai." Shang Chi gets put on his ass.
twice.
How does he do against Iron Fist?
Just as good. Keep in mind next to captain america (who is a supersoldier), Iron Fist and Shang Chi are two of the top fighters on the entire planet. Wolverine is on their level or past both. Hell, he doesn't even need to be able to see to take out opponents. Wolverine has trained to fight totally blind.
his skill level is pretty high up there. Not the best mind you (there are others that could body him H2H) but his combat skills are being sold short. there will be no quick wins here.
