This makes sense.

In my imagination there is a large set of players who “homebrew” stuff because they don’t know or understand the rules, and a very large subset of those players are also disorganized. A sizable subset also just don’t know what the fuck they’re doing.

So they’ll be like “oh we let the wizard attack and cast a spell on the same turn. Is that not the normal way?”

But for people who homebrew with intention and thought, yeah, what you said.
