Your battletag name proves you’ve had your D3 license since before LoD.
You cannot buy a 4 digit battletag when RoS came out.
So pause away and enjoy it.
I did not say it needs to be taken out of the game.
I said for ME it is useless as I only play HC for last number of years.
I can’t even imagine why someone hits pause in game.
It is like a crutch of some sort.
Anyway enjoy it in D4.
