Tried it. Played Quest of the Frozen Flame (or what it is called). Wasn't impressed.
Class abilities was disappointing and not very interesting. I remember reading something like as a Barbarian I could get a class feat that allowed to be intimidating when raging. Whaaaat? Isn't a raging barbarian intimidating by default? PF2 is a game where I feel like I have to get a feat to go to the toilet. Skill feats are even worse and feel like at huge waste of time.
Oh God, I hate the argument of "Isn't it intimidating by default" for two reasons:
1) You're not describing intimidation as much as a morale failure. Barbarians are supposed to be scary because of the damage they can cause... but then again, plenty of different kinds of adventurers cause tons of damage as well. If anything mages should get free intimidation checks given what they can actually do.
2) It's enforced roleplaying: you're not sitting back trying to debuff someone, you're rushing in and hitting them. You're so enraged that it's not about screaming at a guy to get him to flail in fear, you're only concerned with whacking him with an axe. Raging Intimidation is getting back that one braincell that says "Wait, maybe we can scare him first".
Really, the whole "you can't do anything without feats" misses that you largely can, Feats just make you better at certain things or give you definite ways to do things.
The action economy - loved by many - didn't do it for us. In 5e I can drop weapon - move - attack - move - attack - and still use shield. In PF2 that would not be possible in a round. Also as casters the economy just plain feels bad. I'm quite baffled that people love this action economy. I don't like the idea that all actions are equal in value. I don't like this simplification.
Well, you really can't do "move-attack-move-attack" outside of certain circumstances in 5E, and if you don't have two weapons (or a monk) you can't do it unless you are at 5th Level in certain classes. In fact, you definitely can't do it until 5th level if you have a shield. 5E isn't really more fluid as much as it decides to limit you in different ways: PF2 limits your action economy through cost-benefit, while 5E tends to lock that stuff behind specific class choices.
What people like about the action economy is that it's easier to understand and makes more internal sense: it's not that Martials are the only ones who can attack multiple times a round, but they're the ones who can do it
better. You don't need to try and figure out if you can do a Bonus action spell with a cantrip or a full action spell; if you have the action economy, you can just
do it. You can't split your attacks like you could in 5E, but then again attacks matter more and can hit harder by comparison: you're not always benefiting from maxing out attacks, making it a choice rather than a class feature. Sometimes you're better off using a shield, intimidating a foe, etc.
Also I was a convert on the whole "Raise Shield" thing: I thought it nerfed shields, but in play it doesn't and it honestly makes the choice feel significantly different compared to shieldless martials fight.
Then there's the whole caster issue. One of my players played Warpriest and didn't like it at all. They just felt bad and underwhelming.
Well, probably a bad choice if you wanted to be a caster given that they give up some of their expertise to be better with a weapon and armor. They are getting an update, but it's going to be at making them better in martial combat more than casting, which is the Cloistered Cleric's area of expertise.
