First things first: Lol.
Okay, now, I remember someone had gone to a convention or news press of some sort? And the person who posted that thread said he heard that HoC would be leaving. Then DJ Helsing swooped in to say that it was not the case.
Like whaaaat? You know, if he had just confirmed that it was leaving, I feel like it wouldn't be so "sudden". Then at least we'd have over a months advanced notice.
Then people would have the time to get the achievements.
They always do this. Same for that fluff event -_- Shortened it by a couple hours and screwing us over.
