LP LOSS FOR NOT LOCKING IN ISNT LEGAL

there should be a system that alerts you when its your turn to pick or ban when youre tabbed out, league used to just pop back up and now it doesnt, it's happened to me twice in a row before and i dont believe people should be punished for it in ranked its just kind of a big fuck you to the player imo bc its not done on purpose whereas actually dodging is. im sure something can be done about this to make it more user friendly.
