Well, the creators might be wrong. It’s not like the devs can’t make a mistake or something.
And I totally agree with @anon62818569 here; it seems like most people haven’t really seen Scarzig’s video on Blue Conjurer, which is a shame - he very meticulously went through the odds of pulling very good and better-than-average minions via Blue Conjurer and showed, through some hard data, that the problem is actually quite simple - the pool of minions from which BC pulls is just too good. It generates, on average, too high a value. And there’s really nothing more to be said here - AB was a bad idea, Arcanysts were a bad idea, but even compared to them Blue Conjurer was a particularly bad idea.
