PSA: Pro Tip - What it means to "carry" your team.
The carry of your team is the person who did the most damage, not the person with the most kills.
APC (ability power carry) is the champion who does the most ability power damage to enemy champions.
ADC (attack damage carry) is the champion who does the most attack damage to enemy champions.
The overall carry has to be on the winning team and has the most overall damage output to enemy champions. MVP = greatest average champion/structure (turrets, inhibitors) damage.
Not the asshole who has 35+ kills and stopped his team from getting fed.
