So did you mean Eladwen or Nishaven? There are some Nishaven complaint threads too, but he is inferior to Eladwen in most match-ups you will find in Quick Match, so Eladwen seems to be the Hero more...

18 matches against Nishaven out of 20? Really? He is the face of Shadow Era and the default starter deck hero, so maybe that's the reason. Most people are complaining about Eladwen and Darkclaw...
