Yes, add it.
No, its fine how it is.
Another good add on would be including the actual values for each stat on the current 'bar's that show the stats right now.
I agree with this. Besides this, I'd like to see all stats from currently equipped armor displayed on the side (or wherever). I think it would be easier to look at like that. I definitely agree that more information needs to be available to the players in game.
This is long overdue. If they're going to lean into the RPG side of things, this will have to happen at some point.
I'm hoping this is one of the many things that will be added next season. A ViDoc already showed armor stats getting a rework, being more in-depth, and adding Int/Dis/Str. I could see them doing this with weapon stats as well.
