3rd party software !
People have been using those kind of applications for a while and specially one of them is pretty popular right now (I’m not sharing name of the applications).
I was in an alliance and couple people started to use this and they start to collect all the credits from the arenas, gold, 3*-4*-5* shared crystal and anything they can get from the arenas which mean is everything in the game.
I left that alliance because after little while almost every single summoners was using that app. Who doesn’t have enough time or cannot afford to purchase credits.
Honestly there is a lot to say about but all I can say is now they have a lot of stocks and have gotten many 5* duplicated champs.
I’ve been looking for 5* Hyperion and my last four 5* are Kamala, spider Gwen, Antman and Rhino and all of my 5* champs are almost same as them. Now I’m asking, did I make a mistake not to use it..
