Paizo has confirmed that the Centaur and Minotaur ancestries in the upcoming Howl of the Wild book will be large size by default, with a heritage each that make them medium.
Now thematically, I think that makes sense, 5e’s ponytaurs always seemed like a cop-out. However mechanically, large size has the benifits that it allows you to reach more squares, even without additional reach, and makes it impossible for small creatures to grapple you. So I’m wondering if that’s powerful enough to require some kind of downside to balance it out.
What do ya’ll think?
I don’t think you’d need to Squeeze through either 5-foot hallways or normal sized doors. In theory that’s reserved for spaces that just barely fit your shoulders (trained) or just barely fit your head (master).
I’d think both of those would just be difficult terrain. The doorway might be greater difficult terrain, especially if it’s particularly narrow or something. Squeezing is pretty debilitating, since it’s 10 rounds (one minute) per 5 or 10 feet of movement.
