No, it's mostly a problem of people used to their Landsknecht / Savage Horticulturist 134 DPR kukri juggle build PF1 characters who would never miss with their 11 attacks and are now faced with the brain-shattering reality of the PF2 math working differently.
I agree. In PF1e you could achieve similar never miss a skill DC/hit build without getting excessively convoluted; in fact I think it was quite easy to end up with such a build with very little effort. For example you start with the not unusual character premise of "small and stealthy", you pick a halfling rogue, Skill Focus Stealth and 20 dex. Without really trying, your first level halfing rogue has a Stealth mod of +16.
So I think it's reasonable to assume that a section of people complaining about chance in PF2e had, intentionally of otherwise, taken for granted such builds in PF1 and are now experiencing a degree pf edition shock. It's pretty much the only way I can get my head around people complaining about chance existing in a game system based on rolling dice.
