Warhammer appears to be a breeding ground for tags that are either unclear, or too broad. Most notable is chaos (Warhammer), which appears to be for just about any character related to the Chaos faction. This is absurdly broad because it's in turn composed of several subfactions. Just like with SU gem species, it would be preferable to instead have a tidy list of characters and species on a dedicated wiki page.
On the other hand there's Chaos God. This one is instead a small group of 4-5 members, but it gets tagged on every post that has at least one of them, when group tags require the entire group to be present in an image.
Heresy is probably the worst. It's a canon/lore tag for anything that's considered "heresy" inside the WH4K. It's too abstract to be a tag, and completely meaningless to anyone who is not a hardcore WH nerd. There are a few non-WH posts (mostly about giving characters big boobs) with the same problems. This one should probably get nuked, it's worthless.
And then there's a bunch of others like butchers nails, daemon prince and demon primarch. Maybe WH fans can see something I don't, but I don't understand if these are supposed to be species or a group. And what is the difference between death guard and plague marine? These tags need wikis explaining what exactly they're describing, not simply the associated lore.
