Just to iterate, that activity on Ultimate difficulty with matchmaking by itself is hard enough. You're better off not doing it if you're looking for score-based rewards as even the top 550 Power player in a good session might barely get away with a simple B-rank. Anyone who does worse usually ends up with a C+ or lower, meaning that you won't get the bonus drops for getting a B-rank, even at 550 Power. I can only imagine the suffering of having to do custom modifiers to get better score. It's just not worth it. I still think the score system right now isn't good design. EDIT: Also, Contest of Elders is still suffering. I don't understand how you go from The Whisper to Contest of Elders in terms of difficulty spikes. They are not comparable at all, even if the revive issue did eventually get fixed.
