Constant client crashing. [Friends and me]

So my friend has gotten over **4 **15 minute queue dodge times because of league crashing right as we get into the champ select. It crashes not only then but when loading into the game and clicking on the hextech crafting icon. This is a problem for over 15 of my friends and its really hurting our accounts. Its been happening for over _5 patches _now and its getting really annoying. Especially after a game when I click on play again it just completely closes out. The client has been really bad lately and it I think this should be looked into.
