#2 has been fixed in the next patch (reduced elo/gain loss to 10% when RPG is enabled).
#3 should be fixed in the next patch, but has not been tested.
#1 is something I'll look into now, trying to find a good solution.
Edit:
#1: I've fixed the display of team names when scoped, so you should now be able to see them properly (

Edit 2:
#1 Team members will now be shown with 50% opacity when you're scoped (
