By the look of it, Jump Link is not that helpful in any place in Maujak. If you say that you can place it from Watkins region to Mulligan, from Mulligan to near Hackett (Tootega Quest), or even from Grovesnor to level 55 area, then did it make a big difference? No.
Other maps with the "intestine-like design" can easily become playable with Jump Links. While defending, defenders went from one point to another without walking the whole map-- be it in Goldfields, Mokon, Green Volcano, or even Cold Claw Valley, so it is indeed doing the job intended.
Whereas for Maujak, this map is a special case of its own, they will have to redesign the layout of Maujak Completely.
