I too am in agreement with points put forward.Overall, I'm really liking the feature and already crafted my first dragon - the Harmony Knight!! I've always wanted this Green Champ to take out purples in the arena!!?! Thanks Storm8!
As discussed already, Commons and Rares aren't even worth disenchanting... I'm just selling these duplicates now. SRs and URs are needed if you're pursuing a Codex dragon reward. Therefore, anyone have great recommendations on the most efficient way to farm Super-Rares and Ultra-Rares for essence? So far, I'm thinking/using:
1) Grind Fire/Crusader with Diamond... hundreds of 10 sec fails, but eventually a 40-44hr UR
2) Breed Fire/Crusader with Dino... lots of 3 & 4 hr Common fails, some 6-8 hr Rare fails, but then the not uncommon 6 or 12 hr SRs for essence (& perhaps a bonus UR occasionally if using Crusader).
3) Breed Forest with Diamond... some 20 sec fails, and then the likely 26hr SR Dawntree (and only if very lucky, the 32hr UR Queztal)
I'm currently doing #2 unless I'm watching a bad movie on the couch and have time to mindlessly grind #1. #3 is a more a guaranteed SR, but 52hours of hatching/evolving for one SR & 40 essence seems too inefficient (perhaps more viable when Dawntree leaves again).
