We've played the first game together on the botlane and well even the enemy jungler spent his whole time with us the enemy didn't have a chance. He's really good and knows what to do, I would say he can carry games even he couldnt roam really as adc!
But the second game was really awesome, he carried the game solo. He made his enemys really mad: his farm was much better, he pushed toplane till the end after already 10 minutes, he was destroying them really hard and they had no chance. Its one of the best boosters I saw yet, really recommend it!
