A support auto-ing minions for the ADC to farm is a pro level power play advantage. You should really (like, REALLY) consider practicing that because if you do it perfectly, you can achieve leveling plateaus faster for a better timed gank. The new ranking system has something to do with your post-game grading scale--not just your KDA or W:L ratio because in the end, that's just obsurd. Yes, your ranking takes into account those factors but the biggest impact is your grading. If you lose a match and get a 2:1 KDA average ratio with an "A" grade or higher, that match value awards you more points than if you won a match with a 4:1 KDA and a "B" grade. Also, your gameplay mechanics and your TEAM MECHANICS GREATLY AFFECT THIS POINT SYSTEM. Please be aware of that because you can carry all you want--if you don't exercise proper game and team mechanics, RIOT would most likely give you a lower score than one who has a 1:3 KDA and losing match score and an "A" grade. League of Legends was designed with TEAM effort to accomplish ONE and ONLY ONE goal in mind: Destroy the enemy Nexus. There are reasons why each tower, dragon, baron, jungle, lane, inhibitor, and ward objectives are assigned point values, especially when you get to Gold rank and higher.
