We've found over the years that people would rather stay on high population realms with long queues than move to very low population realms. When offering transfers - even free ones - to low population realms, very few people take the offer and high queue times persist. By providing transfers to medium population realms we can, at the very least, offer them a somewhat enticing reason to get away from their long queues and offer relief to that entire realm.
Obviously we're exploring some new ways to solve low population issues in 5.4, and we'll have more details on how that will all work (as well as a final name!) in the near future.
(For reference, the current free transfers can be found on the front page right here.)
