think this as package u send when u walk...
think that "m1" are home point lower jeuno and "m23" mog house.. and every step u take u walk up one m
you = ( )
(m1) m2 m3 m4 m5 m6 m7 m8 m9 m10 m11 m12 m13 m14 m15 m16 m17 m18 m19 m20 m21 m22 m23 m23
now when u stand at m1 your upload speeds goes to zero but u keep walking and when you are near AH your upspeeds goes up again and u will be at (m12) and ppl in server will see u as u jump from m1 to m12
this is exactly how it works with pakage hacking 2 it lies for server that u are on a pos that u dont are..
and speed hacks do the same only diffrent is that they sending all pakage faster then usualy for each move...
squarenix could easily fix so u wont be able to lagg from m1 to m12 but they dont because it would be to laggy for everyone too play...
