As a player with thousands of hours in hearthstone - GWENT feels very freshreshing. I've played the game 5~ hours a day and I'm truly addicted. I don't know what state the balance has been earlier, but now that I started playing it feels pretty well balanced. Sure I can find some imbalanced cards, but there is usually always way to counter those cards without completely cripling your deck. Every GWENT game feels different - and you actually get to play the game (unlike hearthstone where you play vs cancer decks like pirate warriors or something like that all the time.). I haven't gotten salty about any deck yet - I know my deck is weak against some matchups, but those decks have weaknesses that can be countered with other decks. There are so many ways to build your deck and so many working strategies. You can play high RNG decks or limit RNG by building very small deck - however you like it. Try it out - I regret it took months for me to do it even I had beta key waiting for me.
