A moment of silence please. Can you guess this weeks hero? Indeed, Silencer!
Silencer made my list because he is interesting if played correctly, and becomes increasingly more useful during late game. With his abilities he can silence every enemy on the map for over six seconds and then deal tons of damage, and then chain-silencing them making heroes such as Storm Spirit or Pudge virtually useless.
How about permantently stealing 2 intelligence per enemy kill? I had over 40 extra intelligence banked up along with heavy intelligence items dealing over 300 damage per right click. Not bad, huh?
