The other thing 4e did that I miss was entirely self-contained monster stats. If PF2 can do these things, its definitely worth a look from me. But if DMs still need to look up feats and spells before running monsters in PF2, thats going to be a hard pass from me. 3e and PF1 just became too burdensome on me, and I abandoned them for 4e and then 5e.
Abandoning 4E's model of showing all monster capabilities in a concise stat block was a big step back for 5E. And sadly, it looks like PF2 eschews that DM-saving innovation too.
90+ per cent of adversaries and NPCs will have no role in the game besides 2-5 rounds of combat. Presenting those adversaries in a tight stat block that captures the things they'll do in 2-5 rounds of combat is a, major selling point of 4E. It really is disappointing designers turned their back on on a clear efficiency win for the sake of tradition, or that fraction of the player-base who just love building PCs and NPCs as a sub-hobby.
