All these people saying this game has paywalls are just bad at the game I guess? I haven't found a single paywall. I play every day and have made it all the way to 3389 in rankings. All my characters are lvl 8 except 1 level 9. This game isn't meant to be play 1 day rank up to tier 15 it is about strategy and progression. Give a game time.. too many paywall complaints when there are no paywalls. Join a clan fight the boss they improved the gold and now artifact drops which makes the game better!
