What happened to key drops?

Do you have honor 2 or above? Do you occasionally get honored by non-premades?

Yeah but not as often. Riot changed it where you would get more keys, or more chest depending. So it'll take long ex: it get keys because you have 10 boxes

Not really it works evenly, and Riot doesn't want to give out free skins freely to often. They need to make money as a company you know right?

Key fragment drops are dramatically reduced below honor level 2. I can't see your honor level, but maybe that's the cause.
