Welcome to: The Lord of Paywalls: Money.If you're a free-to-play player don't waste your time, you'll regret it.Season pass with OP rewards for spenders while non-spenders get pocket change, way too few tokens for non-spenders(main way to get gear/heroes) with bad drop ratios on top of that, reset of your progress every season (you only get to keep your heroes at level 1 and gear, everything else goes back to day 1).And of course the toxic "tiling" game design.Bad is a compliment for this game.
