Been playing Gwent for two straight years like literally everyday, one thing I know is that CDPR just keep releasing new journeys and new cards but never actually try to balance each faction, all they just want to do is using that to attract more customers to purchase. Every time a new card expansion is released, which means the entire game strategies are changed dramatically. It is of course fascinating to release new cards to make game much more fun to play, however, developer never evaluates and understand how one card (despite it's gold card or even bronze card) will affect the whole balancing of the entire game structure, and the most irritating thing is they never make radically decisions to fix these issues. For example, Fucasya and meditating mage.
This game is going to reach a limit where later on, in my opinion, a 4 provision bronze card can play 10 more points than those gold cards that are released long time before. I'm pretty sure that the designers of this Gwent game have not played this game as much as most of us players, they don't know to what extent to fix cards will bring a true balance to this game. It's future is on a thread, but anyway, this game will never get as popular as game like Dota2 or League. For me, CDPR just lost a royal customer like me forever.
