There you go. That's the key problem with the vocal internet ragers.So till now Duuk maybe right, now they are angry and in half a year they buy the new DLC anyway.
Activision's stock price is going to be just fine once they ship Diablo mobile and 89% of the Diablo fanbase buys it and plays it and happily clicks away at the in-game shop for all of the shiny upgrades and it brings in a billion dollars to the bottom line. Because, after all, all of those ragers DO have phones.
The 11% of Diablo players that don't buy it because it isn't Diablo 4 won't be missed. And the money from My Little Diablo Happy Adventure Island will fund Diablo 4, and when the Diablo 4 trailer launches the 11% will come running back saying "SEE111!!! this is what they should have done before! Our protest made a valuable point!" and the irony will be totally lost on them.
