skill has little to do with climbing.

you can outfarm your lane enemy by over 100, out kill, help every lane, get most objectives, but you still lose cause someone didn't give you their role, or afked, or didn't like mean words someone said and is a baby. Or you can be 3 1 in lane safely farming under tower and your mid/jung will come chase your top under his turret and give a double 3 times making you have to fight a 7 3 lane enemy no matter how much you ping to back off cause ill get em this time!
