Apparently you don't have kids or a job I guess?
7 days out of the week -
First day, you log on and play a couple games. You are on your fourth game and someone knocks on the door.. Do you ignore who is knocking at the door? no.. So you get up to see who it is and it's your neighbor...He wants to borrow something from your garage to fix his car. You go out get the tool and give it to him and come back to the game you are flagged despite coming back 20 seconds after your flagged and carrying your team.
Second day, you log on after work and you play a few games and no interruptions.
3rd day, you log on after work and play a few games. 3rd game in all of a sudden your kid trips and falls.. gets hurt and you have to get up in the middle of a game to check on him. You don't rush it obviously because it's your kid and your kid is more important then the game. You help your kid out, calm him down give him a bandaid and he goes back to playing. You get back to the game you are flagged despite coming back in and helping your team win.
4th day, You don't play.
5th day, you play a few games after work and no interruptions.
6th day, you have the day off you play 5 games. on the 2nd game you get a call from your boss asking your to come into work.. Do you tell your boss give me 40 minutes while I finish this game? no.. He needs you there asap so you say sorry guys my boss called i have to go to work. So you leave the game get ready and go to work, you can't help your team win but your team understands and says it's ok. Doesn't matter you are flagged even though your team mates don't care that you had to leave..
7th day you don't play.
So in 7 days depending on the amount you play even if casual, things come up and you can get flagged for things out of your control. The more games you play the more chances something is going to come up where you have to walk away for a minute.
So what is your suggestion? If you are married , Have a girlfriend, kids, neighbors or a job you shouldn't play this game?
I know for a teenager with no life and no worries, no job no girlfriend or kids they don't have to worry about afking unless their parents tell them to get off the computer.. but for the average person who likes to sit down and relax and play league a couple days through out the week shouldn't have to worry about getting banned or suspended because real life stuff comes up. It doesn't take that many afks to get A long Que time through out the week especially if you play 5-10 games a day. So take your "i'm high and almighty ego " and shove it because everyone who has ever played this game has had to afk or got flagged for afk that was beyond their control and they shouldn't get punished if they make it back in the game to help their team win or their team understands and isn't bother by you leaving.
This stupid system is designed to target ragers and people who afk who don't get their way.. it isn't meant to target people who generally have a reason they had to afk or can't get back in the game yet it still does, because Riot's logic is .. we'll our system punished 75,000 those people who didn't deserve it for afking but it got ride of 100,000 people who rage afked so fuck it it works... and it's less work on us. If the logic is that going afk screws your team and yet you can get back in game and help them win and they were ok with it why should you still get punished? You are arguing logic and logic always wins.
