The AI is Buggy that is Understandable due to the fact the game is so large. But When you call for a copter and It hovers over an Empty paddock, that is just cruelty to me :P
If anything the AI should be able to posses the Human Quality of Judgement. Whether or Not its a Clear Space, or if landing you in the middle of a dam is acceptable. AI will always be asked to be 'Upgraded' and we can never really be satisfied, A) Because where Human, and B) because were all different. In some cases the AI will be good, but tiny little pieces need adjusting. For Arma 2, the AI is good in All cases, but Buggy.
