Riot games throws me out of games and then gives me leavebuster. CANCER

First of all fix the client because it takes so long to load and it also sucks. So Riot Games loves me so much that everytime i am in promo games they just throw me out of the game either with bugsplat or just a crush, the client takes so long to load that i can't even reconect from the bugsplat, now for the crush i can't even open league. You might say it's your pc and stuff like that but nah. I have a good pc and i play a lot of games in high so i don't think this is the prob here. Also how can i only get this when i am in promos? Not only that they just give me a leavebuster for something i didn't even do. RIOT FIX YOUR FCKIN GAME YOU UGLY HUMAN BEINGS, YOU SHOULD HELP YOUR PLAYERS NOT DESTROY THEIR GAMES.
