That is what I am doing, though during the "Find the remaining crystals of Vlast's body" story, it requires you to visit certain places. Some of these green circles (where Vlast's crystals are) on the map are not accessible via a raptor mount, so I need a Springer. Unless I am missing something and not understanding the story. You can get there without the Springer to get the Springer. I am not in the game so my names are going to be off as I haven't memorized anything else so bear with me here. You want to run almost straight west from Lommuld Kraal waypoint (if you don't have it, once you're out of the first portion of the Sacrifice instance, run northward) toward that canyon wall. There will be an NPC with a raptor next to him and some friendly Ogres nearby. You'll see an opening across from you and you can raptor jump over there. The ranch with the Springer is not far on the other side.
