Powers are effectively unlimited; bullets aren't, especially for power-focused classes who use light weapons to keep their cooldowns low. Power combos can do quite a bit of damage to and disable groups of enemies. My Human Adept does a very good job focusing on detonating power combos with Shockwave for dealing damage.
