Let's say a Super AGL enemy has ATK +40000.

If you have a Super STR ally with DEF +15000, the enemy will hit for (40000 * 1.25 [same-Class Type advantage multiplier] - 15000) = 35000

But if that ally had the same Passive Skill as SS3 Vegeta:

[(40000 * 1.25) - 80%] - 15000 = 9250 - 15000 = -5000 (which will result in double-digit damage in the game)

If the event is not particularly difficult, a Super STR ally with a DEF higher than 50000 (40000 * 1.25) will also take double-digit damage, but on something like Super Battle Road, the enemies' ATK is closer to 100000, so having damage reductions can make all the difference in the world. The same goes the other way around, and there are events like Extreme Z-Battles where enemies have not one, but two damage reductions.
