Hello 
I was wondering if there is any detailed Information available, about the droprates for specific loot ( ascension mats, crafting mats, coin pulls) for example from the monster chest, hero chest, titan chest,… as it is available for the raid tournaments.
Hello,… here is the popular one…
Barry Farmz Here – Comprehensive data driven farming guide for Season 3, Season 2, Season 1, Elemental Chests, Atlantis Rises, Missions, and more
EDIT: I missunderstand, I thought it was for the maps.
Monster, Raid, and Titan chest is completly random, and I think unfarmable item droprate is 1%.
Raid tournament reward based on rank, and it is available the help screen in the game play.
Other thing is elemental chest.
Elemental Chest Frequency - days tracking and results > estimated between 4 to 16 days
Indeed the edit contains what I was looking for. I wish it was more transparent. There‘s got to be an algorithm behind that
