Some People Still Don't Understand the Objective of League
Kill the Nexus. Do that by killing Towers first. That's It. Nothing else is important if it doesn't help you do one of those two things in some way. I play so many game where both teams will be relatively even for kills during most of the game but one team ends up domination anyway. And It's because they kill towers after they get a kill (not roam somewhere else to find another kill). Got Baron? Great, you better be pushing at least one lane the entire time you have it.
How has this fact not sunk in yet?
