You were wrong now , but you might be right in the future.
The server structure you described , might be what Blizzard would try at a moment . And (still) having our original servers (but empty) could be only a step to that direction.
This expansion they still keep the original servers , but in the next one they could simply close them .
I guess those 50% hating the CRZ stoped them for moment to completely change the server structure. Too many , and I bet that keep them wondering if they will continue with the plan or give up.
( in every poll [pro] vs [against] CRZ I saw the results being around 50%-50% )
50%- 50% don't give Blizzard any clue if they do the right thing for the good of the game or if they set up a timebomb.
