Why was the Mission Day badge changed?
I still have not done a single mission day since the badge was changed, I stopped at 24.
Why, oh why, did Niantic pick an existing badge that people loved, and replace it with one with so many complaints from agents who do lots of mission days? I still wish I hadn't done any mission days, so I don't have that monstrosity on my profile.
I know many of us are motivated by what badges look like. Some of us spend a lot of money to get a particular badge (onyx MD was EXPENSIVE!), so to have it changed after you've already earned it, really sucks.
