There is something not right about this: “as a user I need to see a login screen..”
Rajan Ayyappan

I don’t see an issue when you say “as a user I need to see a login screen so I can..” 
How would you say this otherwise. And how would any interaction be possible without a login screen, and how should it differ depending on the persona ?
I agree empathy should be baked in, but I also see a lot of useless big user stories that take way too much time and are improper handled by the people actually developing..
