And you are arguing most of my points, especially that the MCU is not the same as the comic book universe. I have yet to see the madder/stronger aspect shown with any accuracy. The closest was when the Abomination held the Hulk against the wall, when the fire looks like it will blowup throw helicopter (2008 film). The Hulk had a burst of strength to get out of the Abominations grip.
I believe you misunderstand, it is the Hulk fanboys who just can live without the fact in mcu that Hulk dont have all the made up powers he gets from poor writing by out and out Hulk writers. The battle ended on a plot device to keeping all of us happy, we can see growth for our favorite characters, and I like the team ups.
