Why was MCU's top tiers downgraded to City Level?

'MAJOR NOTICE' THIS IS NOT A CONTENT REVISION. THIS IS QUESTION AND ANSWER BOARD.

I'm simply asking for an answer. No more. There's enough revision threads already going on.

I just want to know what happened between Large Island level MCU to City Level MCU.

Edit: I'm looking for a brief summary, do not link me to a 500-comment thread.

5 reasons actually:

1. The heat of the neutron star we used was using its average heat instead of what its heat could be thousands of years after it was formed.

2. Surtur never destroyed Asgard, the script says he hit the core of Asgard which caused it to detenote meaning the top tiers are below the attack that killed Surtur (Large Island Level)

3. The storm feats were revisited and the new calcs put it this low.

4. Iron Man surviving the meteors was assuming that Titan's moon was the same distance away from the planet like the our moon is from the Earth, which in this case isn't and is much closer to the planet, giving it lower calcs.

5. The Kree missiles ranged in size from shot to shot and Captain Marvel never really tanked them.
