I agree that "superstition" and "come and get me" are much higher ranked rage powers.
One is that "Come and get me" is basically the equivalent of the 3.5 robilar's gambit feat, and with that feat you could practically smack any opponent trying to attack you and kill them without even using your turn . That's a big boon to melee characters, especially the "tanky" ones.
Second is the "Superstition". Right it hurts them when their allies try to buff them, but its suppose to be a double edge sword in that sense. However, its more of a PRO than a CON, because of the fact of the increasing bonus you have against many Fortitude, Reflex, and Will save spells and ripping apart magic against the "all-powerful casters" . Honestly, its teamwork and the casters would buff you before you raged and while you raged with all the bonus from the chain of the superstitious powers, you will have amazing defensive and offensive abilities against magic (which is a big weakness for mundanes all on their own).
