Any personal preference is a valid argument. And completely agree with Fri13. If only to allow mission/campaign makers a more complete toolset. I would sure like a bit more variety of tasks. (for the choppers section that is) I mean; a million functions and variables to be set, gee, that's an impressive show of dedication and skill. Just too bad most of these functions remain dormant and are only noticeable when the sim decides it's time for a system failure.
So, given that there is a sight in the real life craft, yeah i would definitely dig if there was one in sim. And barrel bombs. Those too. Insurgents and hostile states alike are loving these things cuz more cheap is more BANG for your buck. And more terrified citizens is more Team America coming to save the day! FUNK YEAH!
