So far pf2 the following is more fun....
Three action system....
This is cool as it gives you more options (especially at lower levels) and it encourages more dynamic fights
The new critical system. This is a lot more fun, well it can be a bummer against, but it really can upset fights and makes it more exciting.
We kind of like the proficiency system but we think there should be a bigger difference between untrained, trained, expert, master and legendary. Maybe -5, 0 +2 +4 +6. ....
Shields are cool and actually useful....but a few more dents before broken would be more fun.
Heightened spells, well some of them. Some like fireball really need to scale for free to be useful.
Scaling cantrips.
The idea that sorcerers can use different spell lists than arcane. Cool idea and interesting, but it does need some work.
Less fun....a
Too nerfed spells...
This needs to be rolled back considerably especially the lack of auto heightening for sorcerers, summoning spells (they either need better monsters, more actions or both), wildshape (this is terrible too few forms, too little duration etc.), Animal companions need help as is they are less fun than before.
Since many of us play spellcasters this section as is, is a deal breaker for us.
Resonance seems pointless and not fun.
Character generation is clunky. Ancestry feet's should all be picked at first level. The old tables were easier to read/understand. Character generation was more fun in PF1.
Rareity seems unnecessary. I guess it could be a guideline but it does not make the game more fun.
