How it is delivered
Kirin, Firebird and the rest are not difficult for anybody who has cleared the content once. They are a low percentage on a weekly lockout, which means a year of attempts for one person and a few weeks for a team running it on rotation. The price is the attempts.
It is crafted rather than dropped, which makes it a materials order: a pile of gathered and crafted components rather than a farm. The price includes all of them, because quoting the craft without the materials would be quoting the easy half.
