I am close to quitting as well. I have a build that is dependent on Abhorath and since the updates I cannot ever score a 3 skull drop on a Destroy the World. This is not confirmation bias. How do I know? Because it has NEVER happened since the update. Not once. It used to happen constantly. Now…never. That is a major nerf of Abhorath’s ability, and as my main built up troop, I don’t feel like dropping it and rebuilding a whole new team.
I have also seen my hero’s Bullseye, which is supposed to work 15% of the time, work twice in over 100 matches. It is clearly broken.
I know luck can be swingy. When a Soul Drgaon resurrected 4 times in a row in one battle, I was pissed off, but that is a 1 in 64 chance…bummer but statistically acceptable. The two items above, though, are clear programming errors or AI cheating.
