6v6 + 2 AI players and Other Edits...

I need help. I'm creating an original AoS kind of map but I don't know how to make the map 6v6 playable. I think I have some kind of idea. I want it to be similar to how ToB was with 6 players on each side and then 2 AI players that represent the creeps. If someone could give me step by step instructions that would be great.

Also, it is possible to edit the name of the races for a map? So that it would appear before the map is actually loaded. For instance a player could change their race to something else before the game starts...?

Use Neutral Victim, Neutral Extra

At Map Intilization

set first 6 players to ally/shared vision to Neutral Victim
and visa versa

Set last 7-12 player enemy to Neutral Victim
and visa versa

Then do opposite with Neutral Extra.

=========

For changing races you can in Gameplay Interface.
You can change human to XXX
orc to XXX.

HOWEVER, its a bit dodgy.

If you play the map with these settings, then the NEXT game will show your changes.
Even if you play a normal game afterwards it will now be set to your settings, and revert back to normal for the next game.

Heres a sample trigger I use in my map for setting
