In the beginning Stan wanted a hook to make Thor relatable with a side i.e. Blake who has a handicap. That was common in comics dating back to the start of comics. Part of the problem with Thor was that without that he was simply too powerful on a full time basis. In Marvel that was really a large part of the formula. The problem was it became a tiresome and unneeded devise. I was very happy when Walt rid Thor of it. I was not a fan of the Jake Olson\Thor under Dan Jurgens run. I actually only read vol.2 well after it was finished and suspect it would have been annoying on a monthly basis. I did enjoy most of his run especially before the future Asgard stuff. It would be great to see him finish the arc the way he intended. I was o.k. when JMS brought Blake back but not a huge fan of the idea. I was fine when he was written out again but knew it wouldn't be permanent.
I am waiting to see how the mjolnir stuff works out but definitely sick of anything remotely close to that line. Thor has already covered new ground in this run. I am happy with Cates run so far. I suspect one of the reasons Marvel keeps going back to the multiple wielders and hammers is because it causes reactions and publicity-both good and bad- which means sales. At least that is the theory. That probably means we will continue to see some form of it for a long time. Hopefully not with the real mjolnir which would at least be an improvement.
I actually liked when Thor and Blake were joined, made for interesting stories!
As a surgeon, there were things that he could do that Thor could not!
