personally, I gave up on ability scores.
I just use modifiers.
scores are just a relic, they are just in game to generate ability modifiers that you will use 99% of the time with desperate exception of few requirements that pretend that ability scores are still relevant.
removed racial/species bonuses:
starting array:
+4, +3, +2, +1, +0, -1
(high power campaign: +5, +4, +3, +2, +1, +0)
(low power campaign: +3, +2, +1, +1, +0, -1)
with new feats being all half feats its easy:
+1 or two feats without their ASI's
ability requirements:
13+ -> +1
15+ -> +2
carry capacity:
150lb +/- 30lp per modifier
also, I like the cap of +4 for PCs before any magic or high level class features/spells
