Honor system is slightly patronizing
So about every 2-3 days I get a message telling me what a great sport I am (your teammates have honored you for ____), and giving me a key. I now have about 100 keys because I mostly play the same champs all the time.
If you are trying to reward good behavior, it might be nice to put a little more thought into rewards. Here are rewards that might actually make me feel rewarded, and actually encourage me to bit my tongue during a bad game:
-Reset the "new chest" timer so I can get another chest. -Unlock a "free" chest token for a champ I actually play. -Give a little BE boost so I can buy more champs.
