I've since switched to playing it on PC. The transport helos are dangerous as hell. The attack helos are dangerous, but they are easier to take down because nobody is fixing them in-flight.
Note that I only play in hardcore servers. I refuse to put up with regenerating health and vehicles; that's not Battlefield in any sense and it just makes vehicle combat even more infuriating in light of it already taking 4-6 rockets to kill a tank, even shooting it in weak points or from above.
