Re: Thor's power level
the shield is indestructible. It was just recently stated in the prelude to the dark world, that Odin's summoning of Dark Energy weaken Odin, AND Thor. So thor was "depowered" in the avengers movie.
Now let's look at his feats. a depowered Thor, fights Ironman who is powered up, up to 475%. Thor holding back had the advantage, easily. Even weakened and holding back, he was still way too much for a powered up ironman!
A depowered thor was able to joyfully brawl with, and contain an enraged hulk, and even basically control the pace of it.
I don't know what you are on, but to me, and to a lot of us here, it was made pretty clear that even though hulk is the wow factor, Thor is just pretty clearly the most powerful avenger at this point.
