Last year we got 6 new skins, new icons, an entirely new and reworked map, and patch changes.
What happened in between? All they did was come out with 1 new Hallow themed skin this year, then changed 1 line of code to bring back skins which they said they wouldn't.
They COULD have made it good, but they didn't. Instead they sent away their team to work on some Hearthstone ripoff that's guaranteed to be shit while simultaneously lying to their playerbase for quick cash, while ALSO providing the bare minimum in terms of content.
Oh, and they'll be doing the same thing for Christmas, but I guarantee Chinese Overlords will release some quality Lunar Revel stuff. What a joke of a company.
