From the very start you play well but then after warping over the mancannon you decide to leave the enemy sniper and head top mid. You team seems very static top mid after which you are taken out by the sniper and the rest of your team follows.You have a good Br I would say to work on your awareness a bit more and keep practicing.Good luck.
Good movement getting behind them and getting kills was working well you just need you`re team to not die so much I`m guessing you were and you`re team was - nice job.
