I don't know if I'm doing anything wrong but I constantly see people in other alliances or in the global chat that are about my level and their roster is just significantly better than mine. I always do AW and the 3 day alliance quests to get as many 4 star shards as possible, doing that I get about a little less than one 4 star a week. I don't feel like I can get the 4 star champions in the 4 star basic arenas yet and I'm really lacking on iso to rank my Champs up further. If you have any tips or advice please post them. Thanks.
