If an enemy is not positive, and they get a quadrakill because your team overstayed

The fault is not on the laner. They pinged, they pointed at the minimap, and it was easy to tell with the abundance of wards the laner was roaming.

That's not any specific's laner's fault. It's naivety. Thus, you cannot blame that laner for a fed "Cho'gath" or "Jayce" or "Vayne" or "Yasuo" if the laner kept them behind. It's your fault for overstaying.

But if they failed to communicate...Then you can freely complain.
