the reality is though, seeing and having played hearthstone for years, is that people will build the specific decks that are 'meta' and 'strong' and experimentation dies down.no I don't think so, it's a method to get precisely what you want at any given moment if you're ok with trading down.
I wouldn't have better decks in HS rn but I would be able to forego being able to build certain decks to complete the ones I have built.
Also I'm a spike in constructed I'll always netdecks unless wotc adds an EDH like format.
It may not be true for you, but hearthstone has shown in spades through ever set of cards that people just pinpoint the optimal and don't experiment.
