Do you not believe the PHB rule because I didn't attach a page number to it? I can provide the page number if you need me to. It says very clearly that commoners are proficient with most simple weapons.
It's not true by RAW at all. If you want to call the MM RAW, then RAW says that monsters are proficient with whatever the DM decides. End of story. Nowhere does it limit then to only their stat block.
Whereas I'm using RAW. Not cherry picking what I want RAW to mean like you are.
Yes it is. The standard commoner is a commoner with whatever simple weapon the DM wants it to have. The default block doesn't indicate any kind of standard. You aren't going to walk into a city and see every commoner walking around with a club.
Eh, no. Simple weapons are what commoners are proficient with, per PHB RAW. There is no standard commoner. Stat block =/= standard.
You think a D&D modern game means that a commoner can't use a modern firearm as a simple weapon?
Er.. I'll quote it again with the page so you can believe me this time. 5e PHB page 146. I'll bold it and underline it for aid.
Your race, class, and feats can grant you proficiency with certain weapons or categories of weapons. The two categories are simple and martial. Most people can use simple weapons with proficiency. These weapons include clubs, maces, and other weapons often found in the hands of commoners."
I mean, you can stick your head in the sand and try to pretend that the paragraph there doesn't mean that commoners, which make up 70%-90%(depending on the society) of people, aren't part of most people if you want to.
I'd hate playing in the game you play in. Any game where a gladiator who is specifically trained to use pretty much every weapon, isn't proficient any weapon but the spear in his stat block, would drive me crazy. Games need to make sense.
No. No you are not talking about what makes sense. What makes sense is commoners being able to use clubs, daggers, quarterstaves, light crossbows, etc. The SIMPLE weapons. Hell, crossbows in the hands of commoners was historically something feared by knights in plate. Why? Because it took almost no training to use. Just point and pull the trigger.
What you are incorrectly describing as RAW is a bunch of nonsense. It makes no sense at all.
