AUTOMATICALLY PAUSE GAME WHEN SOMEONE DISCONNECTS?

I rarely have lag spikes but when it happens it often lasts for more than 5 seconds. This happened numerous times in critical team fights in which I would just die after the very long lag spikes which caused disconnection.

If a automatic pause feature like in Starcraft I or II is implemented then the problem with such lag spikes which cause disconnections would be resolved as they would have little impact on gameplay. Why is such a pause feature not implemented?
 

Please Help !
Thanks !

I didn't find the right solution from the internet.
