MLB raising stike zone and Home Runs jump?

As a pitcher what do you make of MLB wanting to raise the strike zone? and your thoughts on the reason behind the huge increase in total home runs hit in 2016 since the steroid era?

Regarding the power spike most analysts believe it must be something with the ball. There are other theories like more scouting for power and players now being aware of attack and launch angles but the analysts believe for that it happened too quickly because it mostly happened after the 2015 all star break and stayed pretty constant since then.
