Some blacklist systems work by using your list as a form of weighting. Adding someone to the list just means you'll be less likely to be paired with them, not that it can never happen, this cuts down on abuse to an extent. You could also limit the number players one can add to it to a smallish number to stop someone from just black listing everyone they can't beat. Or some kind of built on analysis function that checks to see what % of players the person is blacklisting and if it's abnormally high, taking some action. Did Capcom do any of this? Surely not. But the idea of the system isn't bad imo.
I'd like the ability to TALK TO PEOPLE YOU HAVE PLAYED. I get it, it's to keep from getting "hey your cancer" messages.. but just add a privacy setting to only allow messages from friends so people who can't handle that kind of stuff can filter it out.. it would be legit nice after a set with a player you that you really enjoyed for one reason or another, to be able to message them and say GGs and try to strike up a conversation, without having to take their CFN and try to find them on PSN or Steam then have to contact them entirely outside the game you're playing.
