Every sword has 2 blades. You met him (warping) and lets say 20 other non-warping people. He met you (warping) and 20 other warping people. So for you 1 jumped between your tracers, for him 21.
My point is that people who say bad connect helps to get kills shall remember than warping enemy is impacted with same ammount of warps. I do not think it makes that person happy. Of course it hurts the expirience pilot more, than it does the less expirienced one.
It's possibility of intentional warps, but this belongs to "cheating" which I believe is a minimal case in AH, and do not deserver to be spent time on. If you think its the case -- films it and send to HTC.
So, in usual case, avoid fighting with warping person, try to private him and explain him what is the problem (if he is newbie), ask to relog, suggest to check Leph page or other resources to get info on optimizing connection etc.
I was on both side of this problem. I made a rule for myself not to shot down planes which hangs in the air due to apparent warp. What is funny that almost every time I am out of a long warp its "PING-CRACK-BOOM-TOWER". And, what is typical, no one complains while on gaining end of somebody's net problems
