There is one major technical hurdle: EU servers and NA servers are forever (economically) separated by database incompatibilities. Transfer tokens could only be used EU to EU or NA to NA. To add to that, I have no need, want, or desire to transfer from either Nimrodel or Dwarrowdelf. If I should ever succumb to the Big City itch, I can and will simply roll alts there. That said, I hate Big Cities. Dwarrowdelf is a mid-sized city. When I'm there and I'm often there on non-prime times (US) and I've never seen Dwarrow not hopping with ads for instances. I'd guess these instances are not the ones the OP wants at the time desired.

On planet Earth, there is a try.
Indeed, in a world and life full of change, the only constant is human nature (A is A, after all :P).
We old vets need to keep in mind those who come after us.
