nope.. I need to setup a room (Private + only one round) invite a friend, and beat him with all characters in one session, so all characters have a 1 victory on the chart. after that the achievement is unlocked.
The guy that told that has the achievement unlocked but not the 20 ranked matchs achievement so I pretty much believe him...
Do you wanna help Disolitude?
