In need of WoW Info.

What's up everyone! As the title says, I need info on WoW WotLK.
I know most of the stuff but here's my question.Do I need the Burning Crusade level 70 flying mount and the training (900 gold) for Wrath of the Lich King and flying mounts in any way, shape or form?
Meaning do i have to buy it, or can i be cheap and skip it :P

You need the training. You cannot fly in northrend until you hit level 77 (trust me it takes ages, I got WotLK when it came out and I'm still only level 74) and you also have to retrain (1000 gold) and get a new mount. Money is easy to come by in the expansion.

Aww. that sucks. Thanks for the info

didnt know any1 in this forum/rom website or any other type would play WoW
