In a world where dragons, unicorns, elves, nagas and killer rabbits roam, how could you not have included Leprechauns on Azeroth?
With their magic and pots full of magically delicious cereal they’d be a perfect fit! Heck, even that one leprechaun that loves to hoard all that gold in his pot and go on a murder spree if some fool takes the gold would even fit in! He’d just add to the other murderous threats that roam the land.
So next expansion, please add them to the wonderful world of Azeroth! (And no, a dwarf or gnome wearing a snazzy green outfit ain’t the same!)
