I want to believe that there will be a great rebellion against the expansion and/or D4 and sales will be horrible. If not, companies like ActiBlizz will just keep on putting out crap. It just kills me to see such great franchises ruined.
For all that is holy in the land of PC gamers, don't buy their over marketed, shallow, microtransactioned crap release. Spend your money on the great indie games that have been released or on the AAA titles that have truly earned your cash. That's the only way they'll hear us.
