Untrue. If you have no real feedback, you can't min-max your character to the utmost potential. If the devs know you can't streamline your character and play, then they can't make uber-hard, challenging endgame content that requires you to be the best to beat it.
Thus, a lack of metering makes for a dumbed-down, easy-mode game, which SWTOR will not be.
That must be why, months after it was released, fewer than 5% of players have beaten Ragnaros on heroic. Or... maybe you just don't know what you're talking about?
