In my opinion, there are two sides here - the gwent dev team, and the playerbase.
If the dev team did a proper job at balancing the gameplay and the cardpool, the problem would be fixed at the root, and no matter what the players did, Gwent would be in a good state...
But that is not exactly the case, and so we get to the players. They have the option to be creative, find the factions and strategies that they personally like, this would increase variety and hopefully the feeling that the game is stale and you face the exact same decks for week, maybe months in a row would be gone...
That also does not happen. So i blame both sides, honestly.
