There is precious little as to what a fighter can do *outside* of combat...
I will, if after playing with the rules as written I feel like shields could use a bit of a boost.
It’s really impossible to accurately evaluate how valuable that damage reduction will be without the context of the rest of the system. I’m speculating that the damage reduction will more or less make up for the fact that the AC bonus costs one of your three actions, but without knowing what else I might use that action on, what the advantages and drawbacks are compared to using a two-handed weapon or two non-shield weapons, and what PC and monster HP and damage looks like, I can’t know for sure how balanced shields will be. That’s why I said I’ll include it in my feedback if I feel like shields need a boost after playtesting the rules as written. Until then it’s all just guesswork with little evidence to inform those guesses.You mean more of a boost then the extra damage reduction that Paizo have already previewed?
IMO if you want PF to be simpler than 5e, you are barking to the wrong tree. Complex character generation with lots of nuts and bolts is the essence of Pathfinder and something most of PF players want. It's as if you wanted a cat to be doglike, maybe possible, but then you are missing the point of owning cats in the first place.One of the other major critiques of 5E is that the so-called "optional" rules for feats and multi-classing are automatically assumed by default unless the DM goes out of their way to gather a group of players who are apathetic on the issue. Most players expect those to be available, and are critical of attempts to play without them.
Pathfinder 2 already looks to be more complex baseline than 5E is under the most extreme of circumstances, and there's no easy way to turn off those options since they're so deeply ingrained into the core class mechanics.
If by "supported" you mean "explicitly given permission to do," then you are correct. But I'm playing a role playing game, not a board game. I expect to be able to try things that would logically work, rather than choose from a list of preselected actions. See my previous explanation.
