I think Rage will be more dangerous to use when harder difficulties are introduced and the enemy will have more of a chance to punish players for using it. I'm assuming a combination of more enemies and/or higher armors will be introduced and enemies will actually get a turn after players use Rage.
This may be true for Warlord as well. If all enemies are harder to kill, Warlord will give less value per turn.
