Why does the afk counter still go on if you dc?

What i mean by this if you dc from a game, the timer for when you are considered afk for not moving is still going.

So imagine tha youre in the middle of a game. Your team is doing ok, not winning but not losing. Then something happens that causes you to exit the game and return to the client with the "reconnect" button. Like maybe your client crashes because your internet went out during loading screen.

So then you have to fix the problem because you dont want to be the sole reason your team loses. So you finally solve the problem and click "reconnect." Loading screen pops up and queue the elevator music in your head while you impatiently tap your leg in anxiety, hoping your team was able to hold on.

Suddenly "A Summoner Has Reconnected." YES i can make it up to my team and hopefully we can make a comeba-"You have been disconnected for prolonged inactivity. The game will now exit."

So now you have no choice but to click "ok" and disconnect and once again reload the game. I cannot emphasize the frustration i have felt on 3 different occasions.

Like i cant help but slam the palm of my hand against my forehead for how little it makes sense. So im going to reconnect to try to help my team out after dcing because of an unforeseeable and uncontrollable problem, just to be forced to dc again because of a flaw in the system? Logic op.

TLDR-Riot please change it so that the afk timer doesnt count down if we ARENT EVEN IN THE GAME. It would be much appreciated
