I was under the impression it was pulled because of population issues. The cross server grouping system was not ready for primetime & thus putting in ranked warzones would be an ultimate fail just watching 2-4 teams(I'm being generous for the majority of servers) play each other all the time. Ironically this is what is killing this game atm, from a PvP perspective that is, with average pop servers having unbelievable wait times on off peak hours.
The solution as I see it is to properly integrate cross server queuing to ensure someone a playable experience at almost any time of the day. You also need to have server merges, the extremely low pop servers need to be integrated into other low pop servers. This might mean several servers equal only one, meh so be it, a MMO with no one to play with doesn't last long. And like it or not, fail or not, I guarantee free to play has been bandied about in meetings. Love it or hate it, it will increase the player base even if those players do not stick around for extended periods of time.
