Why I set my defense low at the start of the week. If enough people did it, a lot more people would get the rewards. More rewards for lower tier players is better chances for them to move up is potentially more competition.
I saw that before the golden child became OP, just assumed it's meant to work that way. Maybe not.
One thing I've noticed is that sometimes GPD passive just seems to not work. No one blocking passives and have VHE hit him without ascension or chance doing close to 20,000 points of damage. If I've got Eda instead, he'll usually only do about 15K and my setup she's got lower mr and defense. Odd.
