13th age has MID LEVEL progression. splitting the 9 levels gained up into 4 sublevels. In one you gain a feat, in 1 you gain an ability in 1 you gain hp progression and in the last you gain everything else. The progression also is 2 times as steap as 4E and HP and damage gain per level is way more extreme to allow that.
So 13th age is mechanically more like 30 levels than 10.
Kind of the point I'm making.
In 1E you can kill lolth say level 10-14. In modern editions they've inflated her CR.
Similar thing with dragon design over the years.
