As much as I want the feature to hit my realm, I don't mind waiting. Imagine a scenario where they implemented it to every realm at the same time and there's a bug that deletes characters. Imagine the backlash from that.
I'm perfectly fine with waiting while they work out any strange kinks. One positive from the Black Dragonflight/Skullcrusher merge was the timing. It didn't take nearly as long as the first two. Remember, the feature is just as new to Blizzard as it is to us. give them some time.
imagine where theres a scenario where they take 3 months for a process that they said they were going to put in 5.4 but they dident. Imagine a process where a ton of people unsubb from a game because a company wont keep their word and they are on dead realms... these people need to be offered something in return if they have been on the realm for over 1 or 2 years because that is just a waste of $15 monthly they are spending to not get the full wow experience they were promised in the first place. I applaud all the people who are on a dead realm and havent moved yet, those are the patient ones and most have probably quit from the game... i would too because i wont pay $200 to move all my characters, thats outrageous.
