+1 me if you dont recommend your friend to play LoL (say why in comments)
i always prevent my friends from installing lol. because there is no Noob Killer system that locks player ranked mode if they were 1/11 in one game for one day, 3day and ... so everyone comes and feels fun to feed and ruin game, and then one lose get LP as much as one win, and u wasted 1hour of your life (1W +20LP , 1L -20LP) and then you didnt still learnt anything about game, because u got one shotted by the 11/1 enemy . so basically just a waste of time while other free games are out that dont have this problems.

all your item slots when you lose, I saw a couple matches where you didn't even build a jungle item or only had the base jungle item. Funny enough that's more recent as prior to a few days ago you seemed to have been doing okay. It appears you let yourself get tilted off the face of the earth and more than likely become incredibly toxic and troll your team.
