If you think about it right now we have basically the following types of races:
  • Mobile Advancement (fast moving races)
  • Forward Grunt (races not so fast but have good combination of power and health for the front)
  • Defensive Grunt (the counter to the forward grunt similar strategic value but is better when not moving or when camping / defense.
  • Support Class (heals resurrects and provides other tactical abilities which mainly help other classes)
  • Strategic Support Class (Similar to support class but may not actually help teammates directly but has abilities that give the team strategic advantages over the other team usually in the form of map control)

Races are not limited to one type but that is basically the way to strategically understand what is going on in a game and how the races play style types effect where it will normally be found in the game and what it will be doing.
