Riot destroy my game and i got reported for that too!!
So i got a leave because i got a message for no reason "Attempting to reconnect" (My internet was fine btw) so i wait a 1 minute and nothing happen!!
So i close the client and i got the message to reconnect to the game so i press the orange RECONnECT and the screen become black and i got message "You need to turn your firewall bla bla bla" (when i dont have any firewall or antivirus on) so i close the whole game and reopen it i log in again back in and i press reconnect again and nothing happen because i got the same message "You need to turn your firewall bla bla" so i was forced to actually log off from windows (CTRL-ALT DELETE) to actually be able to reconnect to the game and when i reconnect to the game the game was end and i all see in the after screen was my team saying "Report Garen for leaving"
And this is not the first time that this happen this NEED TO BE FIXED already!!
