If your cooldown on Death Punch is at 1, it means you have an INT of 26 or more. It's probably more difficult to get a Warrior up to 26 STR, since they have more useful Talents, and can't really trade in as many as a mage can, AND they also have CON and SPD competing for attribute points as well.
... actually wait, that doesn't matter since STR doesn't boost damage, just chance to hit.
