No hint about that? What for that early? When? When they were going to Zaratras it was a day so this was strong Escanor. IIRC Nakaba only changed 2 SK so far (so small changes) and I don't think there will be any with larger caliber. Remember that we still don't know how Edinburgh's accident...
Useless? I disagree. He might have lose some his strength at least. I think Vampire King knowing that he couldn't kill him with physical atttacks he manipulated time around him to kill him by giving him 100+ years but Escanor finished him off before that happened. Sadly he couldn't get revert...

Don't forget that even King with SK had problems with vampires when Ban used on him Snatch. Anyway, I put...
I am sure that you are wrong. In chapter 103 "A New Journey" we can see old Escanor. I will say it again: Vampire King might be responsible for current Escanor's apperance because he have an ability to manipulate space and time. He made him older. This is the most believable theory at the moment...

Or maybe this Vampire King made him older because (like Meliodas said) he can manipulate space and time.
