I’m going to sound like a jerk, but if you want a pink mercy, go to the OWL tab and buy the Hangzhou Spark skin. If that’s not enough, there are Mercy coloring pages you can download online and color her however you like.
If they brought it back, would it make money? Yes. How much is anyone’s guess, but nowhere near what it did the first time.
Not only that, but it’s not up to Blizzard to bring it back. That lies in BCRFs hands, and they have said it was a timed exclusive.
Sorry you missed out. Your post was one of the better ones regarding this matter.
