I used to be 1st place in Portugal as sniper in Battlefield 4 for Xbox 360 and Xbox One (check battlelog), needless to say I like sniping a lot.
But, despite Ghost Recon Wildlands being a very nice game, sniping is underrated in this game, To able to see a target only about 700m far is unsatisfactory. (Of course, considering the best scope being T5Xi (6x), 700m is not an excuse, mainly because a little further from this distance the target simply disappear) However, sync shots are good (solo or coop)!
As sniper, another accessory that I miss a lot and I think it should be implemented in Ghost Recon Wildlands is a BIPOD, making long range shots much more accurate.
On the other hand, I really don't like the way rebels deliver you choppers: sometimes they place it inside garages, on top of cars, inside lakes, on cliffs... As my primary vehicle, chopper is constantly used (for tactical airborne insertion and extraction) and when I ask for it I would like to use it immediately.
So far, I have enjoyed this game a lot and I hope Ubisoft keeps its good work.
