I'll admit: I have some reserves about some of the maths and other rules elements that have been changed (especially the changes to Perception and Sense Motive) but that's why its PF 2e, not PF 1.5e. I'm excited to see how they play out and figure out how much I enjoy them.
But I have to agree with the OP.
The system looks really interesting. I love the new action system, I love that you don't need to get a maximum number of attacks off in one round to be quite effective. I really like the modularity and diversity of the feats and how they enable you to build a unique character.
BUT. And it is a big BUT. When I look at the feats, and the class options, I'm terribly underwhelmed. Much as I love the ability to have a range of options, that counts for very little if none of the options are impactful.
Maybe we just need to wait for Paizo to release more content.
The racial feats are by and large disappointing and I don't feel like I'm making a choice for most of them. I feel Gnome feats have been done the best, and even then...
The skill feats suddenly make you invest in feats to do things that seem tied in to what the skill should be doing already. The Survival skill, for example, should let you be good at foraging for food, find shelter and the like. And yet I need to invest in a feat to be able to reliably get enough food for myself and a single other person?
The legendary skill feats are also underwhelming for the level at which you can access them, and they're really the first feats that are EXCITING.
Paizo, I really want to love PF2. I really do. I want to have a wide range of options to create a unique character, even if I've done the same race/class combination three times previously. But to do that, all those choices I make need to actually mean something, not just add safeguards to prevent us from critically failing in things we're supposed to be good at anyway!
I don't expect to have the same kind of skill differences as in 1st edition. But at the same time, the change to the maths has made it so that even a character who is legendary in a skill can get a lower result than someone untrained in the same skill far more easily.
I don't want to just be taking options that make my failures less punishing. Make my successes more interesting!
That's my one issue with the Playtest. My options, though myriad, are just not interesting. I'm finding myself pouring over feats to find interesting ones to take, and then having to go back over it to find enough feats to actually fill out my build. Feats that do very little for me, that I'm not interested in, and I don't feel good taking.
The action system is great. The changes to maths is acceptable. I feel like there is minimal impact to my choices.
