You're the one rationalizing what's essentially a free Weapon Focus feat. And that's fine. But your interpretation is not any more correct than mine is.
Not true. Mine actually is correct, and is supported by the rules. Your's is just some "ruleslawyer shenanigans" as someone in this thread called such things.
This is the internet, have an opinion and back it up. Don't be surprised when someone has a different opinion and backs it up. The world isn't full of robots eating vanilla ice cream.
You didn't actually back anything up. You just gave your view on how you want it to work, not how it does work. It's OK if that's the way you want to run it, but don't try to tell people that's the way it's actually intended to work, or somone will have to call "shenanigans" on you.
