How many other classes or races are there where you've found they invariably attract a bad element so you just don't allow them at all?
I tend to be pretty open with character race, but it's the concept that truly activates my suspicions,
Basically this.
I've mentioned before my criminal campaign were no one would do any crime and would always do the morally good thing.
If I run more campaigns in future, I'm going to be strict with character options. I like to leave it open, but there's always some awkward one.
Currently my campaign, though a plane hopping campaign, has a hub city they operate out of, so the ranger is a constant thorn in my side. The player is fine, but his character wants to be out and about hunting deer and communing with nature. He keeps wanting to use his tracking skills. His backstory he is was hunting a monster when he gated into the campaign by accident. So he wants to spend downtime tracking that monster. None of this is bad on it's own, but together I keep having to think of reasons why he hasn't fucked off between sessions. When he makes a tracking roll in a sewer or city streets, I have to try and explain how he follows them, or why he can't when the plot demands it. I struggle to think of some plane hoping wilderness creature that would also be related to the "collect the McGuffin" plot.
Likewise, why is the necromancer, the life cleric, the paladin, and the bard hanging around together. My usual excuse of having a faction with a shared goal is failing. I messed that up because instead of having it be a shared faction to start, I introduce the plot factions and have the party choose one to join after a few sessions meeting them and learning their goals and methods. Why would the thieves guild take a paladon and cleric? Why would the knightly order or knights allow a necromancer and a lute playing vagrant join?
Personally, I'm just racist against the dysgenic midget fucks. Same goes for halflings, and infinitely more so for kender.
Same. I'm pretty open as far as race goes, and there are some fun concepts, but in games that are grim dark or are advertised as having adult themes, short stacks immediately raise an eyebrow.
I also hold this suspicion in adventures too. Especially woke companies and authors. If there's an abundance of short race NPCs, or the art could be read as suggestive or fetishy in some way, I begin to think something weird is going on.
