Legacy people still do have a lot of...how do you say.. power structure that can fall over to non legacy as a bad thing.

This has yet to changed.

One look at a legacy server and you see primals with ilvl90 PFs and 10 twin PFs all over the place. A non legacy server you would barely get enough to fill the spot with ilvl80s and probably the same faces over and over again, and forget about pugging twin.

Legacy independently moving around...sure why not, but there would be a very big fear if a large portion decided to dump on another server (and one with cheap housing prices), and just blow that world to bits.
