Hah yeah that's me. Small world.
You're Tjikkie from Method I assume?
I stopped playing WoW about a year after release though. After a while you start to realise that the game, although very fun the first ~2-3 months, is just too repetitive beyond that and you only keep playing because of the character 'l33tness' and grinding habits.
I prefer short SP games now with just friends on lan (using a program called Hamachi to create lan over the internet) because they don't rely on 4 pounds of heroine pumped straight into your veins to keep your addicted to the game.
Anyhoo, yeah the talent trees could change a lot in release by the looks of it the basic idea of the abilities won’t change. Most likely only certain stats. (Stronger/weaker, duration longer/shorter, etc...)
Still, I usually enjoy the game more by figuring out stuff (theorycraft) rather than actually playing it so you could say I already have the game at the moment. :P
