I've said this way too many times - there needs to be a check before someone Qs for PVP

It is not okay to make someone queue up for 3-10 minutes. Plus ~5 minutes of champ select. Then ~5 minutes of load screen because the player never connected. Then a minimum of 3 minutes before you can remake.

In a BEST CASE SCENARIO that's ~16-23 wasted because the player's Internet/PC cannot run the game and you actually get to remake.

WORST CASE SCENARIO that same player actually connects to the game, and is a burden to their team by default. They sit there either AFK under tower spam pinging their 2000ms ping in chat all game, or they do the polar opposite and end up 0/10. Either way, they waste an additional 12 minutes of their teammates' time and their unfortunate teammates end up with a loss instead of a remake.

Best case scenario, Riot has let someone waste 9 people's time. Worst case scenario, 4 people get -15 LP off pure RNG.

The client literally doesn't even check that all of the game files are present before you join a lobby. Once I had a fresh install of LoL and it said that I was missing several crucial game files AS THE GAME WAS LOADING IN. It doesn't check to make sure that all the necessary Microsoft distributables are installed on your PC. It doesn't recognize that you have 50% packet loss. It doesn't recognize that you have 1000ms ping. It doesn't recognize that you're trying to run the game on a 10 year old toaster of a PC. It is a fucking JOKE.
