Suggestion: Separate Mini-Map Stream for Watching Matches

Suggestion:

There should be a separate stream of the mini-map when watching all of the championship matches. The idea would be to watch this alongside the usual casting spectator thing - either on a second screen (including smartphone/PC/laptop/TV) or on the same screen but in a separate window to watch it side-by-side (on a PC/laptop).

Reason:

It isn't always easy to follow what's going on from what is shown on the stream. Sure, we get to see the fights and stuff, but for strategy in seeing map movement much harder. Quite often I'll be watching it and suddenly three people have appeared to gank a lane, which the casters didn't see coming and wasn't seen on the screen. Usually when this happens, I rewind a bit and try and figure out how they got there, why the other team didn't notice people were missing for a gank, etc.

It should also be quite easy to take the map - which is being streamed anyway - and make it its own stream too. So even though most people probably wouldn't bother, it's easy enough that it should be well worth it for those who do want to.

This is posted here to see what people think and in the hope that Riot see it and consider implementing it.
