I have little to say about the feats chapter, except I have no complaints about it. I guess for me the feats system and thus the chapter are just sort of "there" and if any problems exist with it I expect they'll come out in play. I do have quite a bit to say about the feat system in general though and can only guess that my position will be at least player-unpopular. Still, just for the fun of it, here goes.
Why is there even a feats system anyway? When it comes right down to it, the feats system is essentially a second skills mechanic. Foremost, I believe the invention of feats goes all the way back to a little-known, venerable Dragon Magazine article containing a number of combat maneuvers for 1E fighters, special moves designed to make them more interesting, to make them more than participants in hit point slug-fests.
Unfortunately, since then, the feats system has exploded into a garden of weedy confusion. If there's any one mechanic that's been overwritten, brother this one has to be it. The feats system mirrors no learning system in the real world, so doesn't really simulate anything. Furthermore, the wilder feats in D&D decidedly turn characters into weird freaks. This leads me to believe that the feats system belongs more to superhero roleplaying games where freaks abound. So, I also think superhero games had some influence on the development of feats.
The feats system has caused me so much woe and consternation too that I almost wish it had somehow been folded into the skill system, so we have one "look at what I can do" mechanic instead of two. I've tried to catalog all the feats I own in various D&D 3.5 books as well as enter them into Hero Lab, a project I've at long last abandoned for sanity sake. One man vs. a staff of crazed designers on caffeine meeting corporate deadlines? Clearly, I'm gonna lose.
By the time Wizards of the Coast killed D&D 3.5 there were well over 600 feats in the books I own alone (I have the table to prove it). I hope the trend toward game designers creating new feats at the drop of a hat will stop, but I don't expect it to simply because they're relatively brief, easy to write and fill empty space and sidebars nicely. If we have to have a feat system, then I would much rather stick with and explore the core system and so that's the plan in my future Pathfinder RPG games. I don't know about anyone else, but it seems like we never really fully explored the D&D 3.5 core system, because the newer feats seemed to have more appeal than the basic feats. Whether they really were better or not is entirely debatable.
Anyway with our conversion over to the Pathfinder RPG, I'm quite glad to "reboot" the feats system. I'll be very careful in the future to be selective about which feats I'll convert over and allow for use. My plan is to pretty much stick to the core feats unless there is kicking, screaming and much whining involved. Players continue to be fond of this second skill system and, for better or worse, there's really no going back.
Savage Tide Feats: I did convert the Savage Tide feats in the free players guide from Paizo over to Pathfinder as they were easy to add, seem to add flavor to Savage Tide characters and, best of all, pretty much augment existing skills rather than try to do a lot of weirdness or nose picking (i.e. add superfluous talents).
Skill Tricks: I have a fondness for the skill trick system in D&D 3.5, even though it's yet a third way of looking at skills. One of the reasons I like it is because it's now a closed system: there are only 43 skill tricks and that list isn't likely to grow. In fact quite the opposite.
I also like the system because it interfaces with the skill system, rather than adding more weirdness and nose picking. Skill tricks are mostly practical maneuvers. Many of the tricks no longer function due to changes in the Pathfinder RPG skill system though.
Still, I'm trying to decide where they fit in. Hero Lab has retained the ability to use skill tricks in the Pathfinder RPG so I'm toying with: a) converting them as skill tricks; b) converting them as feats. My wife is also fond of the skill tricks system so I have to admit to some "love my honey" bias in retaining them.
