GrImpartialYou should do what Marxist did with the description of his guide videos and add what you're talking about at what times in the description. This works best if you break it up by class and part of the map you're talking about. (Eg. 10:25-Pushing spire as Scout)
This isn't meant to be a 'class guide' as we have said. The map videos that we are making are general teamplay. This video would have been huge if we went into depth about what each specific class does.
Stuff like this will probably be covered in the class videos.
