What's with these Mods?

The thing about a steady progression is, it doesn't fit from a Medium character's viewpoint. If the creature is twice as big as me I get +1, then +2 if he's four times my size.

But a monster 70 feet tall? Stevie Wonder should be able to hit that size of a target. +8 even seems a bit small. +4 is pitiful, it's many times larger than the proverbial broadside of a barn.

Stevie Wonder would be the only person still in the vicinity if a 70 foot tall monster approached.

And why is the Medium viewpoint more important than any of the others?

Since that's where the most action is.
It stays the same from whatever viewpoint one might look from, though - the 7 inch critter against the human, the 70 feet monstrosity against the 700 feet horror - they all shouldn't have many problems hitting their opponent, assuming they get close enough to attack.
