Similar to how Blizzard's party finder won't put you with anyone you have previously blacklisted. I approve, though this would be difficult for players who ONLY play dps and those who play tank/healer and dps. As we all know, tanks and healers tend to get the most commendations.

So SE would have to keep track of what coms were received on which position before calculating who gets the most parties. Otherwise tanks and healers who level their first dps will get priority over experienced dps.

What I'd like to see SE do is instead make a separate blacklist for just people you find in duty finder. That way people are 'encouraged' to not act like jerks, because eventually, you WILL end up on everyone's blacklist and then "No Parties for you! Make new character!"
