This was already posted couple times but both were from months ago so wanted to make a new post about it.
Title basically says it all near the start of the second set me and my whole team had the drek'ar debuff from his special throughout the rest of the game. Constant health drain and permanent speed down in a comp game and ended up losing the game which was so winnable because of it. 15 minute YouTube video of showing it from a bit after it started until the end of the game.
