So what if Dungeons are instanced, they also said that there would be allot of open world content added to. They said they were going to continue to add NM's there the Hamlet defenses and alot of other stuff that will be open world. No where do they say that everything will be instanced.

Instanced dungeons will not ruin the world feel. You'll still have your link shell and company's you can do all the instanced content with them if you want. For those that do not have a good link shell or hundreds of social contacts, they can use the dungeon finder. I for one have my group of people that I will be doing things with, I don't need a finder, but it will come in handy when i am playing in the wee hours of the morning when no one is on.
