Reasoning would be mostly around population size. Having it on the old system is nice but population size and off prime hours can cause problems with keep changes. Keeping it neutral and allowing everyone to enters gives more chance for that kind of PvP to take place.

This also gives another avenue for leveling/gearing leading to more interactions with the other realms.
