I can't quite get my head around why all rng is considered bad in the community. Sure, there has been bad rng in Hearthstone, like when a piloted shredder dropped doomsayer and there was/ is no mechanism to prevent your carefully constructed board state being wiped.
But now loads of posters are getting all wound up about the new adapt mechanism and how 'it's just rng', but seriously, without some mechanisms that allow you to shape you deck during play hearthstone just become rock paper this deck beats that deck.
if folk really want a predictable rule set with no chance of variation they need to play chess/ checkers/ tic tac toe.
