I am preparing to run a PF2 campaign as soon as possible now that Second Edition on the horizon. This will likely mean I won't be able to make my own campaign, and instead will be running one of Paizo's (most likely). However, I've never been too crazy about sticking to default settings, at least with everything as is. I play pretty fast and lose with canon, to say the least.
With that in mind, I've played waaaay more D&D than I have Pathfinder, and I've grown attached to many D&D staples. Even my avatar here is supposed to represent the closest thing to Dragonborn, being my favorite D&D race (in spite of how s%%!ty they are in 5e lol).
I've started drafting my first homebrews for D&D classics like Dragonborn, Warforged, and Planescape-style Tieflings with concessions to modern depictions. I want to make some kind of Warlock Archetype, and some exclusive monsters like Mind Flayers and Beholders but that will have to wait till I have a better grasp on the rules.
Are there character options from other settings (not necessarily D&D, but more of a wide net of non-paizo material) that you are seeking to "import"?
I'm curious, does your version of Dragonborn have tails?
As for your question, I'd like to try and implement werecreatures, alternate pantheons, firearms and blackpowder weapons, the Slayer job from Warhammer Fantasy (they are SO cool!), Dragonborn with tails, and maybe cambions if I can get them to make sense in the setting.
Apart from those, nothing mechanical. Just custom lore and maybe a slightly adjusted magical presence.
Yes. Dragonborn should be digitigrade and have tails, imo. Always felt weird about the plantigrade feet with big ole claws.
