Just came across a game where one guy was playing Laz with infite cool downs. He tried to be sneaky about it and not use cloak as often as he should but I kept the pressure on playing Meteor Goliath. I heard Laz say multiple times, ‘cloak out’ and he still stayed cloak. Couldn’t kill anyone because he had infinite heal bursts though he tried to be sneaky about it. I suppose playing Laz would be the sneakiest way to abuse a CDR hack but I know absolutely for sure he was using a hack. He stayed cloaked for 1 minute straight and the support was not cloaked.
If I play him again I will upload a video of it.
