KABAL: Mage, priest, warlock

GOONS: Hunter, Warrior, Paladin

JADE: Druid, Rogue, Shaman

Is there supposed to be a common theme or thread between the classes chosen in each faction?  Roughly, it looks like Kabal is about control, Goons is more aggro, and Jade is more combo, but that could just be my imagination, and, of course, there are many ways to play each class.  (and the oversimplification of those three categories is a whole other issue)

Anyway, the reason I ask this is because I noticed something very interesting about how those factions were picked.  They are literally ranked according to how often I play each class in ranked.  I have currently 4 golden heroes.  Three of them are the Kabal classes.  One of them, Hunter, is a Goons class.  My other two Goons classes have 200+ wins each.  But my Jade classes each have around 50 wins each.  Clearly, I enjoy playing Kabal more than Goons more than Jade.  (my collection is big enough that it isn't an issue of accessibility)

Anyone have a theory?  Also, it could simply be coincidence, and it's bound to happen to some of us even if it was 100% random how the factions were organized, but I'm just curious whether there was some sort of forethought to organizing the factions.
