Like what Logerine wrote. Writes who take over a book just kill great storylines and turn characters that could be great into lame ones.
It is like when artists drew Venom after Todd McFarlane's way of drawing it. No, wiping tongue with crazy saliva and the writer adds to it by taken away how we know Venom is like. Look at the third Spider-man movie

. That was bad writing of Venom and came from a writer who did not know what the character is or could be.
Without a great villain, the hero gets lame because the hero has no real challenges that discourage them and readers get bored. Really, think about how writers make Wolverine almost superior now in a fight with his villains. No challenge because the villains have flaws that makes them so beatable given by the writer and make Wolverine so unstoppable in a fight. All of his villains are so lame that he needs to be in other books because unless they make a cosmic-power godlike immortal hulk with mental control, magneto powers, abilities to take away or void out powers, and master of all fighting arts; he has no one that can beat him.
I know my hopes in a better Sabretooth will be lost by whoever is the writer at that time with any other villain they try to make. I just think the whole clone thing is as worn-out as the whole death thing. Wolverine will just keep cutting his head off or some other thing like a weapon that destroys all matter so there is no more healing and coming back.
