As I consider TR'ing a number of character I am caught at how useless some of the past life feats are too many builds. So with tha tin mind I have a suggestion.

With three or more PrE plays should have a choice from three (or four) different past life feats for each class. Each of these Feats should highlight one of the the PrE for the class and than maybe one generic one.

The feats don't have to be over powering but need to bring something to the table.

For Example Fighter

Past Life - Kensei - Plus 1 to hit and damage and plus 2 to confirm critical.
Past Life - Defender - Armor Mastery and Shield Mastery - Increase Max Dex allowed by 1 for both Armor and Shield
Past Life - Purple Dragon Knight - TBD
Past Life - Fighter - Plus 2 to hit and Damage
