to those who are saying they have no desire left after 40.....
the game changes profoundly after 40.... before 40 was all about mostly soloing (really for horde the only great instances before 35 are Ragefire, WC, RFK, SFD, SFK, and parts of SM). After 40 there are a TON of instances beyond that.. the rest of SM, RFD, Uldaman, Zewhatever (in tanaris), Oxonyia(sp?), too many elite wanderers to name (countless dragons and giants), not to mention the greatest part of it all, arguably the only freaking reason to play the game...... PvP...
even on a normal server, you want fun post 40, head off to a smaller enemy outpost.. if you are alliance head out to Sun Rock Retreat.. Horders can run to Westfall... or Duskwood... much of my time is spent killing NPCs, or even betterm looking for flagged alliance and starting shit with them or waiting for unflagged ones to start with me...
admittedly PvP needs more work currently and I think that's what some of you are feeling... honor system is decent but without faction perks kind of useless.. though I am building up some good honor points for when faction perks finally get put in. also battlegrounds NEED to be implemented, because currently all we have are defeding off alliance scum from XR and going into raids in Westfall or Helcular assisted raids into southshore (nothing like a friendly level 45 elite demi-lich tearing up the community).
I do agree that 40 changes the game completely... but IMHO for the better... before 40 the game played like every other grind out there.. just faster and more fun... after 40 the game turns from a grind into a much more action oriented game.. to the point that I wish I could transplant my normal character onto a PvP server.. tonight I am actually putting my 42 warlock on hold and starting up a gnome rogue on a PvP server (Stormforge I believe).
Next time you think you are bored post-40.... do a little PvPing... because that IS the high end game... hopedully it will finish being fleshed out by the next content patch, but if the battlegrounds preview is any indication, this game will OWN all other PvP oriented MMORPGs (re: SWG and DAOC).
