I ended up having it on just one of my main level 70 characters back in the day (Level 70 Human Mage) but never on any of my other chars. Finally when I started boxing I ended up getting Epic Flight for my 5 box Horde Team all with Bronze Drakes from the timed COT runs.

I ended up getting my 25,000g mostly from JC and dailies. I ended up getting 4 of my chars to 375 JC (Costed around 1200-1500g each) but I would farm the JC dailes and get 4 Dragon's eye a day and would sell them everyday (At the time they were worth like 400g) Pretty easy and fast turn around when you do the math. Only took me a couple weeks of barely any farming to get mine.
