I see too much ignorance in your post but I haven't got time to comment it all..

Classes:

Do you really believe that WoW was the first with these classes? And EVEN if that was true, they don't feel like the wow classes.

I would say you need to lvl up some more before making such a negative comment and assuming so many things.. Just a heads up

Like I assume that you have only played WoW before, played a lot of PvP, got tired of the same stuff in WoW (and the fact the game is so easy-mode) expected that GW2 will beat "the best game"(WoW) and discovered it was different.. and I base this on absolutely nothing(nearly)

I feel this game has a lot of potential, PvE is great but I can agree that PvP sometimes feel like a zergfest and I still hope for a /duel skill.. but it's hard to say if GW2 will prevail and stay as a "good game". When people starting getting bored of questing or dinging 80 we will see if the subs starts dropping..
