In case you didn't know, they added a similar system to XI last year with the "waypoints." Waypoints use a kinetic energy charge, anywhere from 1 to 100 units per zap. Kinetic units are refilled by feeding the waypoints crystal clusters. (Light clusters give the most energy.)
Earlier today I finally got around to doing SAM AF2's quest, in which I had to go to Norg, get a KI by trading a chef four gross ingredients, go to Laybyrinth of Onzozo and pop a NM, return to Norg, then tomorrow I'll go back to Norg, then head out to Valkurm Dunes and pop two more NMs, and then finally go back to Norg.
Before, this quest would have been a two day nightmare for a 50 SAM, with having to constantly travel to Norg from Kazham after getting there from a teleport or an airship or from the outpost.
Today, the first half of the quest took me about thirty minutes. I zapped myself to Norg from Ru'Lude gardens, initiated the quest, bought the crap off the unified AH in Norg, got my KI, zapped myself from Norg to Mhaura, ran to LoO, killed the NM, ran back to Mhaura, zapped myself to Norg again, and finished Part I of the quest. Then I zapped myself back to Jeuno. Total cost: 120 kinetic units, or about one light cluster's worth. 5K gil, maybe?
A poor 50 SAM back in the day would have spent around 3-4 hours and at least 10K gil getting Teleport-Yhoaters.
