Kinda my thought? Jason Aaron's (unworthy) Thor is a travesty. And, as mentioned, worthy Thors showing under Ewing against Immortal Hulk was a complete embarrassment. On the other hand, Thors board ruled speed should at least apply to worthy Thor.
Honestly, if I were writing Thor, once i was done with the black winter, I'd find a way to retcon just about everything Jason Aaron wrote and Thors low showing against immortal Hulk. I mean...geez.
