I'm sure they've been trying to find a way to bring back it back since 2007 when it was first removed, much like Player Owned Houses there is a long path from inception, getting the systems to work, and actually implementing them.
I'm not saying they knew it would happen from the beginning, I'm just making the observation that they've probably been trying to reverse it ever since implementation.
I'm not sure that they wanted to bring it back since the beginning. Once they made the decision to remove it they seemed pretty committed.
But, it is obvious that they did plan on restoring it well before the "poll" ever got released.
They were committed, and they even said at the time it was because their other options were not viable at the time, and that they would work to fix the implementation as time progressed.
Again, I'm thinking this was like Player Owned Houses. The idea may have changed, but the basics were there from the beginning until the infrastructure could accommodate.
