So, Kabam has always said the spins are random, with the featured hero spin, a 20% chance to get him. If that is truly the case, then how is getting Mephisto 6/10 spins possible? Technically, it's probably, but highly unlikely. Better chance to win the lotto. And no, this isn't a photoshop...

And from what i've seen and done myself in the past, it isn't random and I kinda know how they do it :-)
