five stars for the game itself, so much potential, should be an app. However, 2 stars for how limited the play is without pay. Think you shot yourself in the foot a bit. Some pay2play is fine, but how overpriced individual buys are for gems does not coordinate at all with the price of decks and gaining gems without paying is so slow and monotonous that there is not much to do without spending money.
People who like it, will likely eventually quit it, because of this inherently unbalanced system of pay2play. It's fine asking money for gems, but you should've balanced it better. You should've made certain tiers for pVp so new players didn't fight rich players. It just ruins the future of essentially a fun and immersing game I still play sparingly. (Though I would change my mind if changes were made, and would buy this as an app for my phone to support you, apologies for harsh review, but I'd like this game to expand and grow, I hope if you come across this you do make adjustments. I think it would expand your audience etc.)
