Shaman had a flavour? 
Hasn’t the class been struggling with its identity for a long time, more or less since the beginning? I’ve also got this to say about it:
As far as I understand, the change removes the problematic bursty OTK-ish kind of deck, but is a buff to something like Reno Shaman — so at least it’s a shot at establishing some reasonable play style for the class.
Maybe it’s still playable, by the way, just not that ‘busted’.
