I am aware a lot of people, especially on this website, don't want to be bothered with playing/making maps that aren't just based in Warcraft. But there is a decent group of people who plays nearly exclusively non Warcraft, IP based custom maps. A lot of models in those maps were rudimentary until filesize limitations were removed by that one update slightly before Reforged's release and the tiny 8 MB filesize limit for Battle.net, but since its removal options for that have largely exploded.
