Dragon,
You are thinking that WoW is going to be something like b.net. Trust me it isnt.
If you have never played a MMORPG and it sounds like you havent then you will be shocked at how much control Blizzard will excercise over people who think they can hack the code and run 3rd party cheat programs. It aint going to be easy especially if what I hear about the game engine is true. From what I hear in order to allow lower end machines to still play they are setting up the game engine along the lines of a terminal services emulation. in other words all your PC has to deal with is the graphic refreshes...there wont be any code being processed on the client side and with no code being processed the servers arent going to readily accept any outside scripts. Could it possibly be done.....yeah.....but brother you had better be good....and then expect your account to be deleted, banned, and fed to the wild dogs......and oh yeah criminal charges presssed against you ;-)
For one we are talking a server wide community (2000+ people at a time) not a simple 8 person "pocket universe" like you create on b.net. There will be loopholes and exploits to be used I am sure but it will be much more closely controlled. For one thing the game will be perpetual.....there will always be someone in the game and it wont be a question of "creating" a game that you can crash in order to perform some sort of cheat.
In any event we wont need childish minds like yours when it goes live so stick with b.net ;-)
