League crashing constantly in every way possible

I know this has probably already been posted countless times, but I am absolutely FURIOUS at the current state of League client. Every single day I play League, it crashes at least 2 times. Twice now in 2 days it has crashed in ranked champion select after the last ban is selected, meaning I'm stuck with a dodge penalty and I didn't even dodge! Not only that but the role I wanted is really hard to get because it's popular and I had finally gotten it. Game will randomly crash if you click Hextech, which has been mostly fixed but it'll still sometimes do it when you click on the store or right after a match. The game will sometimes even just randomly freeze up and crash. It's disgusting and makes the game VERY hard to play when the client doesn't even work. Don't even tell me to try repairing the client. Already done that and it doesn't help. Maybe if Riot spent more time fixing the issues that matter instead of working on more skins and champions to shove in our faces (and yes I know it's probably 2 different departments but if that's the case why is one showing much more progress than the other?). Please Riot fix your client! Or if you're not gonna bother with it, when is the Alpha client I heard about coming?
