My guess is that they’re trying to do it temporarily to boost sales for the WC bundle they’re in as a bonus perk. Blizzard, however, lost the assumption of goodwill by their customers years ago and resultantly, this will not be taken well.
We keep hearing influencers and journalists talking about the various ways games companies screw over their customers. Yet, here we are, and Blizzard is alive and well, and the complaining continues. Is it that gamers like getting abused or is the drama exaggerated?
At the same time, maybe people do like being abused even if they won’t admit if it means going back to the brands that gave them the dopamine hits early on. There aren’t enough substitutes out there for most to walk away.
Have you tried replaying it? You can't even RMB to move units, you need to click the move icon then select where.
Warcraft 2 does not (imho), and last time I tried it, Warcraft 2 BNE still worked just fine, so that's probably getting shut down now.
