I think on of the prime characteristics between a scrapper and a tank is the how strong the character is.
Once you gain superhuman strength, I don't think you can be considered a scrapper any more.
I know that Captain America pushes this a bit, but he isn't throwing cars around.
Obviously, he's shield on some levels, but I think at the core, Captain America is super reflexes as he uses the shield as a weapon as well as for resistance.
There is no good way to cover Cap's shield use in CoH.
And, herein, lies the problem.
In comic book superheroes - to a large extent - don't fall neatly into the CoH classification system.
Part of the way that CoH tries to work around this issue with the archetypes is to allow powerpools.
So, yeah, I consider Spiderman to be a super reflexes/super strength tank with the fighting, leaping, and speed power pools.
Of course, Wonder Woman ...
Blocking bullets with those gauntlets is definitely super reflexes.
Ultra Boy is often uses super reflexes to avoid damage but he basically has the "swap ammo" of superpowers.
.... but, of course, he has the ...
... (originally created by Brainiac 5 before retconning) so he can fly all the time regardless
I think Superman would be built as Invulnerability/Super Strength with speed and leaping/flight (depending on which version of Superman. Originally, he couldn't fly).
Before any retconning, I think Black Panther was around the strength level of Captain America.
I think of him being a scrapper more than a tank.
Is he stronger than Batman? Sure.
But the only thing between Tank and Scrapper is Brute.
I can kind of see Black Panther and Captain America falling into the Brute mold as they do tend to seem to get more powerful/into the the fight when they have more opponent to battle or are in a long fight.
I guess I have to give in to the fact that part of being a tanker is being able to take/soak the damage. The vibranium in his costume/armor really give him that.
So since he is relying on the suit for Invulnerability, I would have to say that means he has Invulnerability.
His ability to leap around and avoid attacks would come from the leaping and fighting pools.
I wouldn't consider any of the Batman family to be tanks.
They are definitely scrappers with stealth if not stalkers some times
Sure Bruce Wayne can pull the Tony Stark and pull out some Power Armor Batsuit, but is that what he does on a normal basis? Not that I remember at least.
For all I know, with all the retconning going on, Batman can fly and sucks blood out of his victims ... I mean ... rrr... the criminals he is fighting.

I've been doing other things, but I think I've put enough time into thought on this post for now.
I had a good time thinking about this one.
I'm sure that there are more characters that I consider to be tanks with super reflexes that I'm not thinking of off the top of my head.
