Yeah.. i don't want to touch the leaderboard, but perhaps i should have used one boost when doing my starry night breeding to get up to mother. But, i think i can still do it, even without more speed breed.
It's only 50 gold right now to activate the roost? Not in game, I'll see if it is on mine too. If it is, I really hope they leave it at that price. 100 is steep, and I only reactivated it after buying it once, to try for valiant. I think, with the roost and the diamond temple, they should have a higher cost to get it initially, and have it lower cost after. That'd keep people from selling off their temples after they are done with them, and probably encourage people to re-use them.
