Endgame Traveler Abilities

Traveler is notoriously underpowered in-game, power crept by 4*s at every element, with little to no exploration benefits. I hope at some point, endgame Traveler is buffed beyond recognition so we can enjoy using them in their full glory once all the dust settles. I thinking unlimited flight, unlimited endurance, quick change element reel, massive strength boost, auto-collection of enemy drops... like give us a reason to keep them forever on our team. What else would you have them do?
