Are G2A Rockets Working as Intended?

[Boomzor]

A few days ago I was standing at the pad of Jaegers Crossing on Esamir warding off all sorts of VS air zerg with a Hawk and yes, barely a third of the shots connected (if that even).
Some of them were flared and others were skilfully dodged so the rocket crashed into the ground or other obstacles, but a worrying amount just stopped tracking mid flight.

Not sure if it has something to do with the drawing distance or what it is, but something is definitely off.
