We routinely faced enemies that had a 75-80% chance of saving against spells and debuff abilities. The enemies also had a 75-80% chance of not just hitting, but critting the PCs. I could see a rope a dope papercut the enemy to death, but it would have very low chances of success.
If those were single opponents, though, the action economy and number of incoming saves needed matters (and the outgoing can be gamed because relatively few opponents in AoOs in many cases). That doesn't mean you can't have some serious risk (in that battle one of the five characters went down promptly in the first round), but just that even with relatively low chances, one thing with 3 actions and 12-15 actions on the other side is not as one-sided as it may appear. (Though I kind of wonder about 75% chance of critting; that has to mean something on the order of a 6 being a crit, which is pretty rare even for a +3 level opponent (I think it would require an opponent with a +24 attack on the average against my current character; a hill giant, which is a level 7 opponent, has a +19; a stone giant, which is level 8, has a +21 (she's level 3). That suggests to me that if you were running into things where your statement is correct you either had an unusually large party (so the opponent uplevelling was abnormal) or you were against things well beyond the range of normal encounters. The same applies to the saves unless you were having to target the opponent's strongest save.
This is not go say that you can't get more crits than you like out of a single major opponent encounter (that hill giant would be critting Jenesa on 11, which is a 50% chance) but just that if your statement is correct there was something wrong with the numbers your GM was using.
There where spells and magic item boosting in 3E that allowed you to do something outside of chargen and leveling to improve your scores. That option is absent in PF2. Even the stats bumps in PF2 just make sure the PCs keep up with the +1/lvl game math. They dont really let you get better at things. PF2 has deceptive bounded accuracy, it changes with level, but always is essentially the same math.
But there are a lot of ways to do small ticks on that; things that leave an opponent flatfooted for example. It really is a game about a lot of characters making the target more vulnerable so someone else can start making its life unpleasant. This is limited and uncertain, but again, if it wasn't, what would the monster level system be good for? CR was certainly nearly useless in 3e by the time you got to moderate levels.
