I'm sure that all of the WCS races were balanced using an equation.
I'm sure that none of the skill design in any of the races were done haphazardly.
I'm sure that people have stopped bitching about the "you know the race(s) I'm talking about" to bitch about how they keep getting countered when playing as said race(s).
Enlightening video though.
Tastes like your moms kisses.
