One of my magor issues with the planned updates is the extention of the party search to what seems to be a cross server model. In my experiance while this may help people find parties quickly, it also leads to a fealing of disconnection from the comunity.
Some people, like me, will still endevore to be polite and do our best but alot of people tend to stop careing how they treat other people in parties if they have no reason to expect to ever see or hear from those people again.
I do agree that converting all the in game dungeons to Instinces isn't an apealing idea to me either. Haveing a large world that at least feels somewhat seamless is something that alot of the plays I've talked to think is one of the better parts of this game. Shrinking it into a series of smaller zones and instinces would seem like a let-down.
