I just want to know from the experienced players if its a good idea to keep going up the leader boards with the league battles. I've been doing it to get the 4 gems per day.
However thinking about quests. I've stopped going up as it puts huge pressure on food reserves to upgrade rubbish dragons. I rather keep the quests for any events that needs quests to be completed ie, Puzzle events.
It costs me 6 gems to reset now, I've heard it goes really high when you are near the top (maybe 27). Are there any other disadvantages? ie running out of league battles / only opponents that is impossible to beat.
