Why I'm starting to hate League players slowly

So I just got into a game (which was a disaster during champ select. Orianna autolocking after someone called mid). We got into the game, 5 mans pass, Orianna leaves because she died to Zed twice and was mad. I recall as Varus bot lane, and my trundle (who I assume is Orianna's friend, leaves the game too). There we were, 3v5. 10 minutes in, a 3v5. Too bad we couldn't use /remake. I really hate when people do this, but I think there should be a way where the game won't count as a loss. This was my rant.
