What's The Point In Declining A Game?

making sure nobody gets put into the champ select lobby while being afk and potentially wasting minutes instead of the 3 seconds the accept or decline option comes up

"Shit, someone at the door. Better cancel before I waste people's time "

You queue up, then your mom calls you/you left to get food before a game is found.

Basically a way to make sure everybody is there to make their selections when the lobby loads up.

expedite the process?

1. it's better so people don't have to wait the whole time it's asking. Similar to how if you decline a surrender, it goes off your screen.
2. I use it when I'm in a lobby that has dodge and people have already seen my pick. It's frustrating to get your champ banned because they unfairly know who you want/are good with.

The reason people decline games (repeatedly) is because they think they are trolling by wasting a minute or so of the life of anonymous people they have never met. Some kids are actually this delusional and pathetic.

As for why the feature itself exists, nobody knows. No other game i can think of have a decline option on queue checks.

The only reason I ever decline a match is if I start the queue and go to edit a rune page and the match pops up a lot sooner than I expect it to and I don't finish it in time.
