I'm assuming the expansion is well into development at this point and things are planned too much to make a huge change to it now.
So even if they agreed to give you what you ask for, you may not see it for months and months.

I love the idea of an open world area designed to be travelled through by 4 man parties.
Put a city at one end, the entrance at the other and DO NOT allow people to teleport back and forth.
If they need something from that city, they have to work for it.

This kinda difficulty could be fun in one or two places but that should be all. If the game filled with them, you'd have others complaining.
