IMO it would be better if most air abilities came in as directional strafes and were cheaper, instead of being the timed auto-targeting loiters. Gives you more control over your target, you can use the abilities more often, and its less punishing for you if they get shot down.
That said, you will miss more often than a computer with tracking would as is now, but I think that's less desirable for fair play. The sweeping mortar nerfs were under the logic of nerfing auto-attack power.
