Warping is an issue that will never go away until everyone is on fiber and less than a mile away from the head-end.
I think warping has much more to do with the person's PC than the actual connection. If I play using my laptop (Pentium 4 Mobile 1.73ghz with 512ram and a 32 meg Radeon Mobility card)
I will begin to warp the closer I get to someone. People with slower systems than this will warp even more so.. There are guys still playing this game with Pentium 3's and old Geforce 440MX video cards or worse. The closer you get to someone (virtually) in the game, the more information gets passed back and forth. When you get within full visual range, the network properties change immensely. So much so that guys will warp above, below, behind, and infront of you when you guys get within 1k or less of eachother. If you notice, when you are farther way (like 2k or more) you don't see what looks like a plane flying normal. You see zig-zagging, warping, straightlines, etc. Then, the closer you get, you start to notice the other planes moving more normally. You get even closer, and someone who's got an older/crappier machine (and possibly a crappy connection as well) can't keep up with all the information that's being exchanged between his and the single or several other players in his vicinity. So, basically, there's a lag time (latency) since it takes the dude who has the crappier system much longer to exchange network information with the other opponent(s).
Basically, these dudes just need to get updated systems, got off dial-up (don't give the BS excuse about how dial-up can potentially have low latency because in all my years, I've never ever seen it) and get with the program. Guys who are utilizing wireless or satellite are pretty much up the creek. Satellite has probably the worst absolute latency times when it comes to gaming.
I think people who are playing on these older systems as well as less-than workable connections truly have no clue seeing that they've probably never seen or never played this game how it was meant to be played and are also most likely computer illiterate. And then again, some dudes just straight-up don't have the cash to get a better PC or a better connection..
Can't really fault these types of people unless they are well aware of what is going on and how the games networking properties work..
And I don't think they are purposely exploiting this either. No one wants to warp. Well, some people might.. But I'd the majority don't know it.
