What chances are we'be been playing Hades wrong?

I remember my friend used to play Hades and he always used to go for that late mythic-boom.

I came across another Hades player who claimed that he doesn't see why Hermes isn't an available minor god.

Moreover deleting shades as you reach the pop cap makes me suspect there is something wrong with the general strategy.

Was Hades originally meant be played like this or did people automatically assume that is how it's supposed to work?
