-.- no, it's actually 10... 12 would have been easy to make as well, but the DotA (*Allstars*) creator has made the creeps on either side Computers... What he could have done was make a series f Neutral Passive units, and set a trigger to change their color (choice) and make them hostile to specific players I.E each player on the opposing teams. I think ToB used something similair to that.
I don't quite understand your Question Fallen... Could you repeat it and be more clear, or someone explain to me what he asked? I'm sure I could help, or if my former explaination solves as well...
