I think that the combos can be devastating especially on harder difficulties because their dammage are upgraded with the difficulty and for most of ennemies in gold/platinium you need more than one of two shot to take them down and then you have time to spam power to trigger combo.

Moreover, a gunnery char type can also trigger combo with specific ammo mod (fire, cryo and tech)
