Delay in game.

yo, i started playing league last week after a year break and i noticed that the game has a lot of bugs, last game me and my friend were playing league and suddenly the game started to Delay both of us. At first i thought maybe its an internet issue but no, it was riot issue.. i wanted to dc and reconnect but what a surprise, i couldn't reconnect. after the game ended, my friend got leave buster because riot games has issues.. i don't get it, very rich company but very bad, i do love to play the game really but the game need to be fixed. Its just like the games has bugs and we struggle because of that, its NEED TO BE FIXED. otherwise don't cut my LP down and don't give me leaver buster, its just dumb, sorry for the language.
