Please don't do this
One of the issues with aram, that doesn't happen often, is people standing around the nexus waiting for the enemy team to respawn so that they can kill them. While I cannot say that I have not done this. I can, however, say that I have not actively prolonged a game so I can "farm" kills in a very one-sided game.
Literally had a game where we were down 33+ kills, the enemy team had killed inhib and should've been killing nexus except they weren't. They stood around the nexus waiting for us to spawn, and continued to do so after the inhib had respawned. Yes, sure minions would've killed the inhib and nexus eventually but even so.
I understand that when you're winning, you're obviously have fun and just want to continue having fun. But when you are essentially being farmed at your spawn, it is not very fun. I believe you should have enough respect for the enemy team to at end the game, especially in a one-sided sitation.
I know that reporting for something like this wouldn't be very easy. (How exactly would you tell?) I guess this is just a plea for the community to not do this kind of thing. It really is jerk move to do. So please, League Community, if you're in an aram and you're winning so heavily that when you get to the enemy nexus, you can easily kill them the moment they spawn. Please do not farm your enemy. Be kind and merciful. End the game. Thank you.
