I don't see the huge threat to the server that a lot of people do with blue transfers and I also think it's retarded for people to feel slighted by players transferring to red "without earning it on red". There are pros and cons to the grind on both sides and no player on blue or red had it as easy as the poeple on red when the full xp bonus was active.

The population increase that you would see with the blue transfers should absolutely trump (in a positive way) any negative feelings you would have about the way those characters got there because the biggest issue on this server right now is population (as long as only no-drop items).

Increased population would increase grouping.
Increased population would help the raid scene.
Increased population would help the PvP scene.
