I'm not happy with the epic feat list. Monks, bards and rogues all got their own class-specific epic feats to choose, but not, say, paladins, rangers or barbarians.
Class-specific epic feats, meaning epic feats that require 12 or more class levels amongst their other requirements, can be considered a class feature, in a way. They're a reward for taking a lot of levels in a particular class.
Rangers should get either improved evasion or extra damage dice versus favored enemies. Paladins should get an increased save bonus from their charisma score, or increased critical range/multiplier when using smites. Barbarians should get increased durability when under barbarian rage.
