"You know I'm glad they reversed their decision but I am not buying the whole technical aspect excuse. they flat out said they wanted it to mean more. So which is it? It was technically harder to grandfather or you wanted it to mean more? Yeah nice try to cover it up."
Cover WHAT up? What are you talking about?

Blizzard still wants the title to represent a significant accomplishment. They haven't changed their opinion on this. They also clearly have decided that taking the title away without at least announcing it was a bad idea. You can expect that sometime in the future they'll still move the title to the 50 reps mark.

In the meantime, the way the current tech works is that the titles are linked to the achievements. You must have an achievement to have a title. When it was moved off the 40 reps achievement, everyone lost it. Blizzard is putting it back on the 40 reps achievement so people get it back. It IS a technical problem. That problem has not yet been solved, so they are working on it. It IS harder to grandfather it in, impossible in fact with the current set-up of the software.

Yes, Blizzard wants it to mean more. Yes, they don't have the tech to support moving the title without removing it too. These are not exclusive. For now, the title is awarded at 40 reps even to anyone who hits 40 reps tomorrow. So what's your problem again?
