This game sure is something else. I've seen so many players get scammed for years by this game and yet they continue to play. With this, more players like myself fall into this trap. Are the crystals set up to be rigged or is it just poor programming? I've been playing since launch and I have obtained ONE 4* Champion, everyone else had to be ranked up or whatever it is. Is there something I'm missing or am I being Kabamed?
Getting anything good out of a premium crystal is pretty hopeless, the odds are very, very low. You'd be better off joining an alliance and getting four star crystal shards from summoner advancement and alliance war, that will get you a four star crystal every other week or so. Just make sure it's a casual alliance and not a psycho one that expects you to devote your life to this. Maybe going for the basic champ in arena too but that requires a decent roster and sometimes way too much time if it's a good champ that is up as a prize.
