There are many programs that will jump gate, its simple to do manually also though, use a speed hack or other form to raise your ping (such as mashing various action hotkeys over and over etc)
then run towards gate quickly, jump it before the gate part shows up and disconnect in air, its very simple to do.
That being said, why does everyone on here feel the need to fuck up the only fun part of the game? Pvp is the only thing that takes the slightest amount of skill and provides the slightest amount of fun... Why would you guys all want to fuck it up? I'm fine with any hack/bot/cheat for anything but ruining pvp is just annoying for everyone involved (aka speedhacking in pvp, teleport melee'ing, aimbotting etc)
