Halflings (Warhammer)
Remember back when Warhammer Fantasy was about combining history with criticism of the modern world and comedy while adding stuff "inspired" by the young and evolving modern fantasy genre alongside Tolkien, the works of Michael Moorcock, Glorantha, and Dungeons & Dragons all for the purpose of selling models of the aforementioned IPs? Don't worry, Games Workshop doesn't either.
Halflings are a remnant of the older Warhammer, mostly forgotten aside from those moments that modern writers want a touch of levity. They've appeared off and on throughout the years, but never once in the starring role of anything. They were more or less removed from the game September 9th 2006 with the release of 7th edition by virtue of not having rules, officially removed in 8e by virtue of not existing in any rulebook and the Dogs of War army no longer being supported by omission in the core rule army list. The last of them perished in End Times, and as one would predict they were not brought back for Age Of Sigmar nor in any sort of demand by the fans of that game.
