I've always had my beef with metrics in general (imo, any focus on anything other than win rate is harmful), but backed down because Wn8 has actual statistical validity and methods. It has value, especially as a tool for XVM to ballpark player competence. Wn8 creators say that Wn8 is not designed as a recruitment, comparison, or Epeen tool...yet we all know, that's not the primary use of Wn8. Instead, people use it to compare each other, to judge recruits, and to track progress. And when it comes to those uses, Wn8 just isn't effective. Its heavily biased by tank, tier, and role selection.
