At worse, the drone jumped 3 plane lengths from where it was due to the manuvers the lead plane and pilot were pulling and a poor connection or lag from one pilot or the other. Also, what are your video settings at?, since many pilots are experiencing stuttering and video problems since the latest revision at higher resolutions.
What I saw was mild compared to some warping that occurs from fighters in the arenas.
Hitting the drones is probably a good tactic if you catch a buff driver unawares. When the buffs are manuvering, it's probably better to take out the lead plane.... when it goes down, the buff driver will have to bail to another ride, there will be a slight delay, and often some warping.... gets worse the longer it takes the pilot to get into a new plane as the wreckage from the first falls.
For a MMOG... what you saw and experienced is a slight annoyance, but a simple limitation of connection speeds, lag, and throughput over the net. It is quite possible that the problems with the drone position was at your end of the connection, since the lead buff was pretty consistent in it's position. I don't know enough about HT's code to know for sure how they prioritize the drones.
You want rock steady targets to shoot at, stick with a combat simulation against AI's with no online component. You play online, you we get warping, discos, and whole menu of problems that go along with it.
Buff drones do have some limitations in movement, which is why buff drivers loose them when they draw too far away from them. Violent manuvers with buffs do tend to result in drones warping or stuttering sometimes. Could they be tweeked to limit it? Probably.... the buff catch up speeds is the easiest I can think of...... but compared to the folks with poor connections, or who "wiggle" their connections every time they get into trouble.... this problem is minor.
