Yeah it all reeks of another corporate misconception fiasco. They talk about how there's a waning interest, yet then they decide to shut down the one place that still has dedicated fan traffic? This is nearly as bad as their convention pitch for Immortal, it shows they have zero clue about what kind of following their own franchise has and that they don't even give enough of a damn about the IP to invest in it properly.
If you have a place where fans are pushing out new conversations and class builds for a game that is now SEVEN YEARS OLD, that in and of itself proves there is still viability for it. I hate seeing a place like this close up just because a bunch of executives speed skimmed a financial report and then threw the word down the chain so haphazardly that everyone suddenly thinks the Diablo fanbase is a dying horse.
I think you may be misunderstanding something. DiabloFans is run by Curse - not Blizzard.
