Here's my biggest problem with this entire scenario:
Bioware, happy to release paid server transfers after over a year of describing them as, "in the works" charges a modest fee of $20 per toon. Not bad, but not cheap. Low enough to entice a transfer or two, but not cheap enough to bring about major server population swings. This would undoubtedly be presented under the banner of, "Trying to keep current server populations/communities relatively stable and intact". A noble goal, of course.
But then in Aug/Sept the, "PvPers are going to wet themselves over this one!" patch goes live. Low and behold, in 2.4, cross-server PvP is implemented and it effectively makes every transfer that anyone paid for up until that point absolutely worthless (I'm assuming that the only legitimate reason for even considering transferring would be pvp community, aside from wanting to reunite long lost alts I suppose).
A d ick move? Yes. But something I could easily see Bioware doing at this point; milking this game and its paying customers for all their worth while the show is still up and running.
