Agree with you, I was hoping they'd at least do something extra, or add back the first Halloween features which were removed in the second one (MOBA minigame, for example).
1. Well ok. "Blood and Madness". I couldn't even remember that the first Halloween had a different title. Silly me.
2. I agree. To this date, I don't understand why they removed that game last year. And it would have been smart to add these features again now that they didn't add anything else.
