Guaranted 5* with high chance 6* can't be salty at all, especialy on nutaku even if you roll a dublicate.
It's salty in the way not everyone will got the same thing. Like the infamous christmas 5*6* ticket with 50% of rainbow. I didn't say it's a bad thing at all, I just say it gave salt to arround 80% of the player base. It's still a great compensation anyway. But not everyone is compensated in the same way at the end, that's just what I'm saying ^^
