It would be abused.
Now if they'd make the leaver lose more (a lot more) LP while the rest of the team loses less it could work.
And with losing more I mean that it should hurt a lot. 40-50LP upwards if you do it more than once a month. Why make it trigger only on your second leave? Because sometimes there's actually an emergency (fire breaks out in an apartment nearby like what happened to me once, a medical emergency, etc.).
"But how does this prevent abuse?" you might ask. It's simple, ask yourselves one question: Would you be willing to lose 40+LP just so your friend loses a few points less?
But again, all of those systems ignore one thing: Now you gain LP if enemy has afker. If any system is added that prevents u from losing LP if you have afker they MUST make it so u dont gain LP if enemy has afker. Would u be willing to allow enemy to have power over your LP gain?
