League of Explorers ticket dates

I noticed while playing through League of Explorers that the tickets on each wing appear to have a date stamp on the edge.

Assuming these numbers are intended as dates, is there anything special about these dates that they would be chosen for each wing?

hearthstone

Each date was a significant announcement/release milestone for Hearthstone.

Temple of Orsis - March 22 2013, was the date of the original announcement of Hearthstone.

Uldaman - March 11 2014, was the release date for Hearthstone.

The Ruined City - December 15 2014, is the date of Hearthstones Android tablet release.

Hall of Explorers - April 14 2015, is the date of Hearthstone's release for mobile devices (iPhone and Android).
