I had a badge but now it's gone.. sup with that? :(
You earn badges with honor, what you usually get early in your game career, but when you reach the end of lvls, etc. 25-30, people stop honoring you, and that is the reason why your badge goes. I was wondering it too, a few months ago, I had the same situation, and I was wondering, but I googled it now and apparently you lose badges if you dont gain honor...
Thats bullstuff, because many people who ask for honors usually dont get them because "One who asks for honors, doesn't get them", and even I have said that phrase.
Riot should really make a thing in the start or end screen where it shows that "Remember to honor your allies / enemies if they have done a good job on their role."
