Here are my two cents: AAA (88 mm) are reasonable, but not critical. Level bombing airfields from above 3K is a relatively safe feature. Attacking low, by yourself is suicidal. But it works both ways - don't you want your resources, that you possibly brought from 100 km, to be protected from enemy planes? It also encourages communication among each other. I found a certain level of enjoyment while supplying. Flying low, navigating, if supplying a village, trying to find a suitable landing spot, and then get a decent reward in points. All of this just gives an additional aspect to the game. The developers of the server are trying very hard to step away from the arcade mindset. There are plenty of other "fly and shoot" servers, this one, however, allows you to think at a tactical and operational level. What I also love about cargo missions, is that you can take off, take care of stuff around the house, come back 30-45 minutes later and land. Everyone benefits.
