I am possibly one of the most upset at the change, if for no other reason than the timing. If I had altered my timeline slightly, I probably woukd have made it just under the wire, but having bred similar dragons on DS, I planned to do it Friday night while watching a movie with my sweetie. Alas they changed it mere hours earlier and it was not to be.
That said, I in no way blame you or any other player. If you had the perseverence/gems/luck to breed an entire island full of them, that would be your right to do so. Probably the reason players have focussed on breeding them is like you said, to make plenty of coins for food, expansions, habitats, etc.
And, like you said, we should all have the same opportunity. TL has heard us, but instead of responding by making it right, they have responded by making it slightly less wrong.
C'mon TL, you clearly realize it wasn't to your benefit to keep things where you put it, but why not just reverse your decision & put thngs right? It might mess with your numbers slightly (animal proportion-wise) but it will probably be worth it to your bottom line just to put things back.
To be brutally honest, I don't particularly like the Emerald. I do, however, need it to earn a few more coins for food, expansions, habitat purchases, etc. Equal treatment for all, TL!!!!
