I think I will just take a break. The whole thing is too complicated, and spending gems to chase dragons I already have is pointless. It's a collecting game, there should be some advantage to having a large collection already.
When I was a beginning player, I would often look forward to the time when my collection was larger so I could participate in more events.
And orbs, yea, these are hugely annoying too. It's hard to get excited about getting 2 orbs: "I have 4, got 2 more, only 94 more to go! maybe I will get to claim this dragon sometime in the next decade! yea!" not so much.
And (off-topic a bit) every single one of my heroic race chests has been a dissapointment, too. Lap 16 now. Not a single one made me feel good.
