The game just crashed before i could pick a champion and it lost me LP and gave me a leaver buster

So i just started a ranked match and told my team i was going to pick my main witch is And they all agreed, When it was my turn to pick my game crashed and when i re-logged i had a ban and had lost LP.

My point is you should be able to re-join the room if your game crashes so you don't get a ban or lose LP
