^ I relooked at the fight and from what Thor was saying, it amps Mjolnir in someway? Thats what it sounds it like anyway. The belt amped Thor's strength, the shield protected him, and the gauntlets increased the power of Mjolnir. Thats what I think anyway.
The entire ending of WBH ended stupidly. I would have loved to see him challenged so I would get an understanding on how powerful this version of Hulk was. We can't use She Rulk because she was amped to be his equal. We know he was far above Herald level since Heralds couldn't even get his attention but him being rocked by someone and having to struggle to end an opponent after a loooonnng fight would have been something nice to see.
