Fix Level 50 Dungeons

[Jim_Berry]

The 51-59 dungeons are already part of Leveling Roulette. However, the 60 story dungeon is not, since it does not give exp.

Hmmm! I never see them in roulette, always got Aurum Vale as the highest dungeon in Roulette.

We also need the Heavensward dungeons to be included as a Roulette. Outside of leveling and story progression, there's no real reason to go back to them (a Lv57 player mostly would never queue for Dusk Vigil for leveling purposes).

But they are already in a roulette.
