As someone who came back form not playing for a long time (a little after pvp came out I quit). I decided to level a new character instead of starting on my 50. 1-50 ARR was pretty boring because I knew it. 50-50 was REALLY boring until the last quest "game of thrones" esque. Heavensward has been really fun, can't speak on stormblood.

TL;DR I'd love to be able to skip the "patch content" story of 50-50 and (i imagine) 60-60. But other than that, the story is fun to go through, and unless you're absolutely wanting to only do endgame (Weird choice for an MMO if that's all you want to do), you really owe it to yourself to go through the good story.
