As I’m wont to do, I was reminiscing about Street Fighter II and how they awarded extra points for Perfects – so how about ISO bonuses for certain achievements (e.g. taking no damage, winning without giving the AI any turns, winning in under a minute, winning using only match damage / no (active) powers) during a match? Or maybe not per match, but as a one-time trophy system?
Your only reward for winning a match with no damage is… increased scaling! Hooray, you win!
(applies to PvE only)
i think some rewards based on how big a cascade you cause would also be nice.
