"To carry games as a solo lane, just roam/tp bot"
If my botlane already died 4 times before I hit level 6, what the fuck is my presence gonna do? Enemy 2v3 and get triple kill, meanwhile enemy mid/top gets free farm and huge turret damage. Even if the roam works, I still lose about 10-20 cs, and my bot will continue to get shit on and feed more because they reset their gold bounty.
