Auto-fill support should be removed
As an adc main, auto-filled supports make me rethink why I'm an adc main. I know blaming others is bronze and bla bla bla but let's face it, a good adc will win with a good support and hold it with a bad support, a bad adc will hold it with a good supp and and straight up feed with a bad support but that's not the point.
The point is: auto-fill supports don't know what the hell they're doing; the don't engage right, protect the adc properly or even peel for the adc. Example: I just played with a karma support that doesn't main supp really. Half the laning phase she was just standing behind me at full mana and didn't want to poke or do anything while thresh was throwing hooks all the time, the other half I was dead. Mid game she told me you suck and left bot lane to support the jungler. After the game I looked up her match history and guess what? Every time that player played karma support, her adc lost and fed the enemies, exactly like me.
TL;DR: I feel like auto-fill support thing should be removed considering how they turn a game into hell for their adc.
