"We tested it extensively and were happy with the level of difficulty when we released it".
Proceeds to nerf it twice in 12h and might nerf it further after the weekend.
I want to clear this up because it sucks to see our QA team taking the brunt of this when they work really hard. Extensively tested means that it was tested to confirm that it works exactly how we wanted it to. It was a choice to make them difficult, not an oversight. I imagine that difference won't make the experience more palatable but at least you shouldn't blame QA.
