First, I want to say thanks to everyone for all of your feedback. It's been great.
Now the part you really are interested in. :) We've removed the exclusivity on the Adventure Act reward dragons. Noxwing, Solreign and Quetzalcoatl can all be hatched from the random 3-pack dragon eggs just like every other dragon now.
Originally, we kept these exclusive to make the act rewards really cool, but the feedback was super clear: That reeks of pay to win. That was definitely not our intention and it's our bad, so we fixed that up.
If you're in-game now, you 'll need to reload the game before these changes are taken into effect.
Thanks again and keep the feedback coming!
