Our support recommends posting my problem on the forum, so I copy my words here:
here are 2 types of upgrading items (
star quartz \i lost 3000+) and (
meteorite crystal \i lost near 500). I know that there are chance of success in % , but why i cant upgrade 12\12 losing so many resources when other players lose at maximum 500 quartz and 100 meteorite crystal to upgrade all equipment ?why this game so cruel only to me???
