Hopefully laziness is. What usually happened is a single mob going through and being implemented a while later, when modders implemented all three in a day or so. Also it being a yearly even instead of being more often. Ultimately mob votes led to 2/3rds of the people being disappointed and some boring mobs winning over interesting ones by slim margins. Also, the implementations of the mobs were really basic, with little to no effort being put into it.
