I don't mind you have to grind this much for a mount, because this is assuming you're doing it for your main character. However, my concern is that items such as orchestrion rolls are untradable and are market prohibited. I'm someone who loves decorating and hunting for glamours, not only for my main character but also my alts. I was honestly pretty disheartened you have to complete 60 FATEs to get the untradable scroll in a zone and then multiple FATEs to get orchestrions in cities like Old Sharlayan and Radz-at-Han.
My point is that they really should be more careful when considering certain rewards because a lot of players, especially those from Crystal have 1 or more alts.
