Diseased / Dying / Replace?

Transplanted this laurel a year and a half ago, and seemed to do ok, but noticed the growth this year is quite sickly / diseased. Possibly a root infection of some sort? Prune? Or is it a goner?

thanks!

 

Looks like one of the fungal/bacterial spot diseases, but perhaps that is only symptomatic of larger issues at the soil level. The weather wouldn't be helping with these... My inclination would be replace, but it would be helpful if others weighed in.

 

AFAIK, during the summer laurels like sunny spot. Your photos look like there is pretty shady. Laurels get infections easily, if there is not enough direct sunlight available. The worst combination is moist, warm but shady.
In winter laurels are happy in much dimmer conditions, provided the air is cool and with relatively low humidity.
