As a clan leader I have to say that your algarithum is terrible needs to be fix why do I get mostly maxed card players when most of my card are level 11 and a handful of level 12 cards like what the alg. is trash, updates are slow and the challenges to win prizes are really bad why would I waste my time for just one token reward for each class rank like what that's not even worth the time wasted to do the challenge come on guys the app use to be fun but now not so much I may unistall the game
