Age of Ultron

But now comes Age of Ultron, the main event of 2015, and promises an epic fight between Iron Man and the Hulk. Obviously, in the comics, even when wearing the Hulkbuster suit, Tony Stark never defeated the angry World Breaker.
Yet again, we can say that this is the MCU and that the Green Goliath's powers have been greatly diminished. Still, he is the most powerful Avenger originated from Earth. So we expected from Tony Stark to put one helluva fight but, in the end, to be defeated.
Was it so?
Obviously, it wasn't. While the scene in itself was actually very cool, how can Hulk be defeated with a single punch? What is the point of having unlimited strength if a sucker punch is all that is needed to knock you out?
Is Marvel trying to say that an 11 foot tall suit can bring down a monster such as Hulk, when a massive Leviathan stood no chance? What's next? Hawkeye taking down the Hulk on his own?!?
