Dailies
Heroic Mana Tombs (very close to being able to summon Yor which will make it ~25% more profitable to run.
Heroic MgT (amazing for prismatic farming)
Heroic daily (assuming its not something like SH or Crypts)
Normal daily (if it can be done in the heroic like MgT)
PvP daily if it is AV

I try to do dailies + 1 heroic at minimum each day, this translates into about 1.5 to 2 hours.
