Seems like you don't like mmos after all, things being somewhat static is a necessity since new players must get the chance to experience the content as well as you.
What I find surprising is the wild expectations some people have to BW and TOR, they expect a Skyrim like game, online, where you can change the environment. It's just in the nature of mmos that those kinds of things will very rarely be there, if so very limited or instanced.
Don't think GW2 will do something crazy with "dynamic content", it always sounds good when they hype it but it will be limited, I can almost guarantee it.
