Ambushes are still very much possible, you just have to use "unrealistic" tools to achieve the element of surprise. On 2238 it's "OH SHIT, we've just turned this corner and there's, like, 30 guys waiting there!", on FOB it's "OH SHIT, we just ran after this guy and now there's, like, 30 guys rushing us from the worst possible directions". It's just more arcade-like, nothing to feel offended about. Also, sneak ^_^ The only bad thing about FOB fov is the fact that you can't check your line of fire, hope there's some tool in FOnline that says "you can fire on this hex" or "you can't fire on this hex" when you click it, but it's no really the fault of the devs.
