It's always when I wanna browse some stuffs like Champion info, or window-shopping through Riot Store in search of a good skin or w/e. But all the time, when that douchebag 10th dude didn't accept/declines the match, the client will always kick me off all the way to the main page. And believe me, it's a real pain in the ass to find back where I was before.
This is just a simple change. Whenever the match is left hanging til it has to reset to find other players, can the client not back me out & just let me continue what I was doing, instead of kicking me off to main lobby.
