I have the Hydra at level 80 (closed), the Centaur open up to level 80 (with level 64 closed) and the Pegasus open up to level 86 (with level 80 closed).
My priority is to open as many levels as possible, to close them when there are pfs available.
I hope that the next Era continues, as far as GBs are concerned, with this requirement. In this situation, Innogames listened to the players.
