Clarity: Carrying and Snowballing Are Different
Carrying is when you are ahead enough to make up for the weaknesses for your behind team and play well enough to win team fights and the like and "carry" your team to victory.
Snowballing is when you are ahead enough to be able to demolish opponents by yourself and are way more powerful than them, and will continue to become more powerful.
If you are a a 8/0/5 Quinn who is demolishing squishies by catching them out, you are snowballing. If you are a Brand with 200 cs at 20 minutes who just dominated a team fight your team was losing because of your AOE, you are carrying.
Keep this in mind when you are frustrated after losing a ranked game that you were doing well in. Which were you doing? How could you have tried to carry rather than snowball?
