I like being able to flag something as OC but it assumes good faith. I'm not sure how useful tagging something as OC is, I'd often find myself look at the person's post history, linked websites, etc.
Sure, charging a reasonable price for additional content is fine. This has been happening for decades as expansions.
This feels particularly odd because Overwatch previously had events (Summer, Halloween, etc) where they released PvE content for free and the community loved it. I played a fair bit of Junkenstein and Lucio ball, it was exciting when it happened for a limited time.
I hope the missions have enough content to warrant the $15 USD price. OW2 disappointed me and it feels like every news article continues that trend.
