if we get a new world boss in Heavensward

What would you like it to be?
I personally wouldn't mind fighting Ghost Train.

Phantom Train is already in the game (it was the nickname given to the secret Garlean railway that runs between Castrum Centri and Castrum Meridanium - you can run along it's tracks to zone between Northern Thanalan and Mor Dhona).

But in keeping with the topic at hand, (spoilers for 2.55):

A two-part FATE consisting of sellswords sent to collect the bounty on the player's head after heading to Ishgard - defeating a certain amount would then attract a unit of Crystal Braves. Defeating the Commander would win the battle.

Of course this could only take place in the new expansion areas and not in the existing areas, given the requirement to have finished the 2.X storyline to access the new areas, but this would be an interesting way of 'keeping relevant with the story'.

I could also see Chocobo Eater making an appearance.
