I was thinking it wouldbe a good idea to have the loading screen double as an interactive map, so you can get to know the space you're playing in/plan with teammates before a game started
By interactive I mean being able to zoom on certain areas, or rotate the viewing angle.
The map would still be wire-frame (like the buildings on the loading screen)

Thoughts?

That's a pretty cool idea, but I think it could be a bit unnessecary. After a couple matches everyone will know the maps and all the spots anyway.

Most people like to be able to jump into a match and start shooting as soon as possible, without the delay of scouring a wire-frame map pre-match, that is almost like a tease.
