Question regarding purchase of game.

Ok, Ive sat around for a day on different forums asking for buddy keys, and can't wait for much longer.

Should I just give in and buy the game?

I played WoW for a year, recently sold the account and want to start up on something fresh, but my question is this.

Should I sit around and wait for a buddy key, buy prophecies (sp) and see if I like it, if not its only $20, or buy the trilogy (thats assuming its cheaper than buying prophecies (sp) and then buying the other 2 if I like it) and just hoping that I really do like it.

Buddy key:
Free to get and free to download game
Waiting around sucks
May only get it for Nightfall, which means I cant try any of the prophecies (sp) classes (or so I'd assume, I really wanna try ele :P)

Prophecies (again, sp :P):
Not TOO expensive
Nice professions range (unless I am again mistaken in that any game (NF or the other one :P) can utilise the ones from here)
Nice starting area (I played the beta a while back and remember a large forest intro VAGUELY)
Wouldnt leave me broke if I didnt like it

Trilogy:
Biggest range, would give the best feel of the game (imo)
Kinda 'spensive, would leave me broke if I didnt like it.

So there it is, broken down, gimme ya thoughts :P

Sorry, didnt see sticky which sorta explains exactly what has been asked here, and have decided to buy Nightfall.

Lock thread please :P

Seeing as Prophecies is so cheap, IMO you should get that first or in addition to Nightfall. You'd be missing out on a whole bunch of skills with just Nightfall.
