yes, is broken, is a build that does too much and you don't have too think, just hit buttons, get close to people and they explode, I remember that mirage was also completely busted a year ago and you could just mash all your skills and get kills, it's mostly the same with scourge, when I just want to relax I just create a level 1 scourge, get the meta build and just around killing people
it's funny that the counter to scourge is to run around and try to decap as much kitten as possible, you can't win a teamfight against a scourge
