I am sick of so many legends that I’ll never get points to train (or level beyond the first three stars) taking up valuable space in my roster. I’ve gotten better about avoiding events which would generate a new dragon,but the DF event is just the latest in which I lose yet another spot to a dragon I’ll never get to train or max.
If it matters, I am a casual player who doesn’t want to pay money for runes or anything. Everything I get in the game, is through grinding. My strategy has me saving up 4k runes about every 45-days or so then splurging on the premium draft.
