Well done on heroic race updates :). It is more feasible/realistic that players can reach lvl 12 and lvl 15 for high dragons. I notice a maximum drop rate before a cooldown period on different quests, with farms full and unlooted, gold full and unlooted, etc...

Looting food Farms: 9 Fruit drops then no drops
Looting Gold from Habitats: 18 Rubies then no drops
Feeding Dragons: 18 Bugs then no drops

What is the cooldown time when the drops stop?

I also notice no more than 3 league battles at one time. There have been times where I have fought 6 leugue battles in a row without spending gems for a battle refill, but only receive quest credit for maximum of 3 in the heroic race.

Any thoughts, suggestions?
