Starting again from zero, it's sometimes require luck to progress higher in the league, but ones you get to a certain position it's hard to earn points for the heroic race dragons

Most players struggle with leagues at some point, but then find them easier again. It is important to choose a strong basic team of legendary or heroic dragons, that have a wide range of elements, that you can get multiple stars on by breeding or trading orbs. Train and feed them to level them up, and get them battle experience to A+.
A strong team of level 50 dragons will be hard to beat, since the opponent dragons are all capped at level 40 (though they do retain their stars).
I use L70 kratus and supersonic, with another in training. My second uses L50 high arcane with L45 yggdrasil and high portal, and rarely lose now.

@justin-tejome The number of the league fight has nothing to do with your opponents. You get opponents who are at the same level as you are or a bit higher. No matter if you are on zero or on 300. If you have problems there, try not to level up too quickly before you have a strong fighting team.

Does anyone know how to edit your age? My brother accidentally put in the wrong age for my account.

@crisonurping You can only ask the support for a new age request.
