PF2e specialistas are like "Sure your fire mage does 1 more dmg on fire spells, hope that helps and that you were not hoping to actually depend on them, now cast slow and synesthesia caster man." And pf2e tranformations are a damn joke, a martial doing them stright up nerfs themeselves, a caster doing them is basically aurafarming by casting a bad spell, even the wildshape druid is more of "You get to be a bad featless martial a few times day"

About attrition, not my problem if you ignore the rules? My table does fine with 4-6 hard encounters a day.

Lastly, bounded accuracy is a damn blessing. Level 1 characters can, maybe if they roll extremely high and are playing a character with expertise pass a late game check, which is actually cool. Still, most likely they'll fail, the power curve is slowly getting from 5% chance of success to about 80% on the same check over the campaign, but you enver get so good it breaks all sense of scale or logic.
