I'm not sure if the PF2 = super heroes is correct. I think it just represents a different way view the fantasy genre.
Having rapidly changing to hit modifiers might be considered more 'accurate' than the bounding accuracy of 5e.
Using a book of NPC I have (Nord games to the rescue) we have a half -elf fighter who at level 1 has the following stats
Longbow. Ranged Weapon Attack: +7 to hit,range 150/600 ft., one target. Hit: 7 (1d8 + 3) piercing damage.
Longbow. Ranged Weapon Attack: +13 to hit, range 150/600 ft.,one target. Hit: 9 (1d8 + 5) piercing damage.
So from a newbie to pinnacle of half elf powers the odds of hitting a target goes up 30% (1 point represents 5% on a die).
What those stat blocks don't show is that the number of attacks increase along with a lot of other combat abilities come into play.
Though I don't have a official PF2 example. We do know that allowing for perhaps 1 attribute increase from 1 to 20th level the standard half-elf state would probably look as follows
To hit Dex Mod + Level + Training
So a 1st level fighter trained with a dex of 18 would be
4 + 1 + 2 = +7 to hit
and s 20th level fighter would be that had an attribute bump
5 + 20 + 8 = +33 to hitWhich is a 130% increase (1 point represents 5% on a die).
What you don't see is that the fighter does not gain any more attacks (barring possible unknown feats I guess).
How super powered is a 130% increase compared to 30%? Perhaps not as drastic as it looks
Lets imagine a single heavily armor target with an AC of 18
A 1st level character in DnD Land will hit the target 50% of the time
But the best archers in DnD Land will now hit the target 80% of the time and get three shots at it.
A 1st level character in PF2 Land will hit the target 50% of the time on the first shot, 25% the second
But the best archers in PF2 Land will now hit the target 95% of the time, 95% on the second, and 95% on the third. (assuming that 1's always fail)
Not too different, the key difference is that experience matters in PF2. So a expert fighter in PF2 can essentially dodge the incoming arrows in PF2 better than in DnD.
Now it gets a bit tricky since different targets will have different training levels in armor.
We can take the these examples. Imaging a target dummy in plate mail (untrained), vs a wizard using mage armor (trained in unarmored), and a fighter (Legendary)
The target dummy is AC 16, the lvl 20 wizard now has AC 27, and the fighter has AC 34
95% of the time, 95% on the second, and 95% on the third. (assuming that 1's always fail)
The odds of hitting the wizard is AC 27 are 95%, 95%, 85% (He should have heightened the spell)
The odds for the fighter are 95%, 75%, 50%
Compared to 5e the archer is not much more of a super hero against a trained foe, but damn good against untrained targets.
