I just play Ranked 90% of the time nowadays...
I'd rather get abused by a Plat/Diamond+ player who actually has a reasonable foundation on which to build a proper (or at least factual) argument instead of some Silver/Bronze/Unranked kid who doesn't realize that me 'not helping him' roughly translates to 'you fed your lane before I even finished my first jungle clear and at this point I'm just going to be a double kill if I try to help your lane'.
