HT put night in for the same reason a kid pokes a monkey through the bars with a stick. It's fun to watch you squawk and flap your arms in indignation.
I think night definately has a place in the MA, but it sure would be easier to defend it if icons were reduced in range, there were spotlights, night friendly instrument panels, landing lights, and so on. I look forward to seeing what they do w/ AH2's night, I'm sure there will be some of the above enhancements and when there is, some of the whining should subside.
