Just read that news update thing on the homepage of LoL about the honor but doesn't give any feedback as to if we're getting anything as a reward for good behaviour.

Does anyone know if we get anything or if it's just to make us play nicer?

Are you expecting a reward for behaving exactly as you should?

remember back in either christmas or new year where they gave rp to summoners that were "good" and upheld the summoners code, my guess, those rewards at those special times will now be given based on honor.
