Not at all sir. As either of my characters can get 10 medals with minimal effort and a dedicated healer has to TRY to get 6+, this would not be fair. I dislike the medal system, and adding more medals will only make WZs worse.
After Valor60, you tend to not care about medals and you just want a win anyway.
My proposal
1-if you did not start the match, it will not count towards your daily/weekly
2-let people know if they're going into a match in progress
