Ryujin
Legend
Dragon's not really the worst offender anymore, given the shear number of feats obsoleted in essentials (generally by purely superior feats and or those with easier prerequisites). But since it's pretty much purely digital I wouldn't shed a tear if all the worthless stuff therein was either brought in line (every at will with rare exception should deal 2x die damage at epic) or removed entirely if worthless.
Consider all of the feats that were pretty much designed as obsolete. Here: You can either have a feat bonus that's conditional, or the same feat bonus that's constant. Which do you want?
