I'm sure all of the augments have some use, but as far as I know most of them aren't game-breaking (except for a few like DRG hands and Angon) and such things. But I personally do Dynamis on my PUP, THF or BST; but I have +2 for RDM and BLU and want to +2 pieces for DRK and a few others. Should I have to waste my daily tally and join my friends in dynamis on a job I'd rather not take into the zone for whatever reason just to be able to store it?
