Each Legendary uses Gift of Mastery and Gift of Fortune along with the respective gift for the legendary. There seems to be unfair difficulties for certain legendaries as opposed to others. 
For example, with current prices, to make the Unicorn statue for the Dreamer, it would cost (at current auction prices) 17g. While, the Juggernaut’s Vial of Quicksilver would cost a little over 200g to make.
While antagonists would say: “Well stop being lazy and just farm the items.”This is easier said then done. There are multiple discrepancies with the ability to obtain certain items as opposed to others as well as the factor of the droprate. Certain items do not have a specific mob that will drop the item you are trying to acquire, such as Silver Doubloon or Unidentified Dye. 
While Legendary items are meant to be difficult to obtain and be for only the exalted few, I feel it is a bit disheartening that that is not the case for every legendary. It is not Arenanet’s job to control the price of items in the Black Lion Trading House, but the way to acquire certain items needs to be looked at.

*Disclaimer: I’m not asking for it to be easier for everyone, I’m asking for balance. If that means increasing difficulty for all, so be it.
