Difficulty Gap level is way to big to play In beginning of some chapters you can spend weeks !!! Once you stop spending money in game you just stop your progres Sorry I need to edit my rate is -100 * Once you upgrade your heroes you can put them in the bin cause New heroes are way too much overpowered and you can have 2 or 3 Star mythic Tank and someone with mythic New Tank can easily surpassed you in campaign because he upgrade new hero to mythic stage 😂😂 Thanks for your money now go home !
