( feel free to tell me how stupid and wrong I am)
Nah, you just prefer Bethesda style of doing things. Nothing stupid or wrong about that. I disagree, but that's just my opinion

And yes, if you can get writers from Obsidian, go for it Bethesda! Skyrim's story was... Well, it had an excuse to kill dragons

Or the people responsible for the game mechanics. Or, well, pretty much anyone except the ones responsible for the world design

Then again, letting them work with Bethesda world designers might result in a bit more believable world while keeping Bethesda expansiveness, so yes, hire anyone you can from Obsidian
