In my case I used to went jungle with no smite cause it was better to do damage with ignite, and I was always wondering “why I don’t get levels?”
Adding that, I used to use flash to get to lane faster.
My friends didn't fully explain items to me, so I just kept buying Doran's Shields on Renekton. Ended that game with 6 Doran's Shields and no idea what I was doing.
