Should be able to get new dragons by using their shards to summon them. Or by making it a game of chance, add an roulette to the game where we have to use dragon shards to spin a wheel for a chance at unlocking a new dragon or by missing completely and only getting resource tokens or maybe a chance at some extra gems. And by using dragon shards, I mean make a new currency called "Dragon Shards" by being obtainable only by placing in the leader boards of a finished event. Say you place 4-10 you'd get maybe 1-2 shards. Whereas placing 1st you'd get 5-8 shards. And it costs 1 shard to spin the wheel. I think that this would keep people in the game longer than just coming on, starting new research or upgrades then logging off. Gives everyone a fair chance at getting shards. But, knowing the company side of this. You'd want a microtransaction. So say to get a spin it'd be $.99. 3 spins $2.99 etc,etc. You get the idea. Instead of collecting shards for dragons that you may never get out collecting shards for dragons you've never heard of, give us a wheel of chance.
