I think the problem exists because by the time you reach level 60 you shouldn't have to deal with all the frustration of playing with a newbie. Everyone should be experienced and know how to play the game by then. Jump pots upset this balance by bringing beginners up to the same level that other players worked and learned their job/role for. Its not really fair to the vets to demand that they now run content with people who can't even perform. Especially if the vet is a DPS who had to spend an hour to get in a dungeon only to get stuck with a sprout tank who doesn't know their role.

Personally, I think jump pots should be limited to players who already leveled at least one job to 60 the manual way.
