So, stuff. It's a hand to hand fight in which neither opponent gets anything from claws to gear. It seems like saying the word Wolverine is basically a reflex tap to mention "also he can cut class 100 bricks with his claws", but they're not even being discussed here.
More to the point, the idea that the nuke thing isn't so out there as to be why we have things like SMvFL, or the sort of thing Wolverine took an actual depowering from, but instead something that can just be proclaimed "it counts because I want it to" as long as you can do a successful ask for it, is certainly interesting. That you could use it to say "well it makes these other out there showings now reasonable!" instead of just being an out there showing of no worth whatsoever is pretty well off.
The standard of "Wolverine recovers from being skeletized in minutes at most" is the standard of "Deathstroke hits Flashes and outdraws Superman". In which case, Logan loses to lightspeed blitz, I guess, just to be consistent (hey, I'm being reasonable, after all, ftl is the "extremely high end". Therefore outreacting near light sorts is now moderate by comparison). Or hey, maybe the showings like that make Deathstroke being so fast he could toy with the Cassandra Cain Batgirl a legit moderate showing for him by comparison, and Wolverine can't hit him anyway (they do not).
Or.
"What level are Deathstroke's enhanced reflexes at for this fight, since they, like his tendency to actually use his superior abilities to hit FTL speedsters and outrdraw/outmaneuver the near light crowd oscillates a lot depending on era, circumstances and writer, going from the extremely low end of Batman being able to land hits on him at all, to the extremely high end of basically casually shanking a straight up demonstrably superspeeding Wally West such that Wally could not see the hit coming or avoid it?"
If we're going to have standards consistent with the ones in your post.
Barring that, Deathstroke's strong enough to do things like kick a steel door off its hinges and deform the door by doing so. Wolverine's tendons have the durability of tendons. If he crushes them, that's considerably ruining them, not "squeezing his wrist" as far as the downplaying. Captain America himself is strong enough that crushing Wolverine's tendons is more than "squeezing his wrists", instead of, you know, the thing he actually did. I'm pretty okay for some reason for a move like that impairing Wolverine long enough for Deathstroke to land other blows to other places unfortunate to Wolverine, like his neck.
I know this whole "Wolverine having any trouble at all with even Captain America is a ridiculously low showing and I'm going to imply he should really be more treated like some verging on Thing scale brick for what injuries should matter to him" is a fairly reliable stance from you at this point in Wolverine threads, but your usual "Wolverine's higher showings* are being ignored over his lower ones approach", as far as rolling that way in a thread with Deathstroke? Means nothing but that to be consistent with your logic for Wolverine getting lowballed, Wolverine is fighting an at minimum well beyond Batgirl's own reflexes meta brick, who he'll thereby never hit.
*which in this case seem to translate a lot to things like "anything below Wolverine coming back from a nuke is now reasonable".
