I will have to disagree on that.... You can still solo carry but with playing with your team without doing it at the same time.... What i mean by that is, Winning your lane, then roaming to grab assists, letting your team getting stonger nonetheless. Doing that, you gain gold, XP and your team doesn't fall behind. Even if without you they are trash, with you, they are strong enough to peel for you so that you can sweep and clean up a teamfight. It's better to have less kills but a team that won't die easily and then snatch all kills later that having everythng in the bginning and lose the game eventualy.... Capitalize on your team's strengths and damage, guide them and then take the game. Carry them without much effort. Win the game on your own but make it so that you don't struggle much. Your champion has 4 abilities but make it so that you have 20 effective skills in your disposal. Use your team if they can't carry their own weights. But don't waste too much time. It's no use to roam when your bot or top is already too far behind.
