Well, game is designed to earn money. If you are not satisfied with the gems coming from leveling the character, then quit the game. Hope you can find a great game that is total f2p and don't need to put much effort to access great success!
Im F2P too. You need to be smart. Dont build any of the current "meta" deck. Try to spare gem and collect "universal" cards. Later you will get some F2P deck and with that you can climb up in ranked. Dont worry. You can enjoy the game without pay.
