You're talking about a fight where Deadpool purposely tried to avoid harming Daredevil, you do realize that? Deadpool doesn't need to run away from Matt. Not even if he's fighting him in the dark. Not even if Silver Sable is helping Daredevil. Once Deadpool is serious he can and has taken the best MAs in Marvel. (please log in to view the image)
You can't lowball the hell out of one character then make up excuses for the other one. That's his skill level right there. Well below Batgirl's. (please log in to view the image)
She treated him like a ragdoll at one point. Which is not surprising considering we're talking about a guy who needs to be at his A game to defeat Nightwing. (please log in to view the image)
Team busting is all he's got. Outside of JLA/Titans plot jobbing Deathstroke is not all that impressive. Meanwhile Deadpool's CIS is the one thing preventing him from ending Captain America's life. (please log in to view the image)
Daken DID use the vanishing trick to get the upperhand. How the hell is that an excuse when we're talking fighting skills? Daken has also nearly chopped Spider-man's head off using that same trick. He would also murder Deathstroke before Slade could blink so I don't see how it helps your argument.
If you actually read the fight you'd know that Deadpool was beating Moonknight in h2h without much trouble while holding back. There's other context which you chose to ignore to suit your argument. And for the record, if you're going to lowball a character try better. Moon Knight without his armor and unarmed has had an upperhand against Shadowland demon possesed Daredevil. The same Daredevil who defeated Iron Fist and Shang Chi at the same time and who would roflstomp Deathstroke with zero efforts.
Again, Deadpool has beaten Captain America, Wolverine (more than once), Taskmaster (4 times, once without his hf), Sabertooth (twice), Omega Red (who would murder Hawkman and Deathstroke at the same time), Deadpool has fought evenly with Iron Fist (even when Avengers showed up to help Iron Fist), he's held his own against Daredevil and Silver Sable at the same time, he stalemated Killmonger, beat Crossbones, recently put up a fight against King of the Dead Black Panther while barely trying. Meanwhile, you've got nothing outside of few PIS/CIS low showing to back your argument.. good luck with that. I like Deathstroke but if you need to lowball other characters to make an argument for him you're not doing a good job.
