No you can still get all 3 if you have Stainglass? Do you have any of these habitats before they were taken down? If so, then they will still hold 2 dragons and 10 gold each. It's only 1 dragon and 5 gold if you buy the habitat now..
Yes that would be best! Then we would have an extra habitat to buy.
I am glad I got on here and found this out. I was about to break down and spend my hard earned gold on Midas. I was waiting for a tree to clear before I bought this habitat. Now I don't think I will bother to buy either. There are plenty of other dragons I still need. I am disappointed though. I don't think making things in the game worse helps anybody. Overall I love the game and have lots of fun playing.
