The machine gunner missions work a lot like CoD missions of the same type so I guess being good at those sorta games helps but it feels off in an AC game you're right.

Scripted dogfights were annoying the other major issue was it felt like especially over Washington DC that you actually got very few kills unless you relied on DFM which was fine because it looks cool but frankly irritating when you're 10km from target and firing 4AAM in to them and hitting trout all.
