You aren’t their boss. You don’t get to approve anything they do. You don’t make any decisions for them. They don’t have to “justify” anything they do in your eyes.
What business is it of yours, if Blizzard wants to ACCEPT MASSIVE PLAYER INPUT demanding they change the rules (because of the pandemic) to relieve hours-long queues? What business is it of yours to decide HOW they do that?
I am extremely grateful that Blizzzard has done this very good thing for players. How dare you attack them for not inventing “perfect rules, with no downside”?
