A424: That depends. If the feat you're looking for is a ranger combat style, or a maneuver feat, or a style feat, then there's ways to grab these without their prereqs (respectively, ranger or slayer or nature fang druid; maneuver master monk or blood conduit bloodrager; and unarmed fighter or many styles monk). There's probably a few other examples if you can be more specific as to what you're looking for.
