Bring your A game into ranked please.
I'm pretty chill about stuff as long as you are putting effort forth and contributing, but if you are gold x playing like bronze 5, there's gonna be some sass going around the team. Stop bringing your scrub pal into duo to try and get him out of silver 5, stop first timing champs in ranked, and stop trying to 1v3 the bot and mid lanes because you went 3/1 in lane. If you are getting smashed in lane, back off and let the first turret go without dying 10 times. By all means do not go gentle into that good night, but understand that if it's gonna happen with or without double digit deaths, let it happen without a team gold deficit larger then the national debt...
