No its good game design to lead players from quest hub to quest hub so they don't have to look up on a web site where they should go.

Also its not on rails because you don't have to quest for exp if you don't want to. You can queue up in the content finder run a dungeon for exp. Just think if you had the content finder in the current version and could queue up for totorak you would be getting a lot of exp from clearing out the place when you were lv25. ARR is suppose to have more dungeons for leveling purposes.

You can form a party and grind mobs if you want they said this will still work but questing would give you more exp.
