But that wouldn't really..... do anything. If it's totally optional, it doesn't serve a purpose. In GW2 those mounts have specific abilities because they were designed to help you reach certain areas of the game. The Springer especially, the rabbit, is meant to jump really high because a lot of areas in GW2 are very vertical. It works for that game because that's the game it was designed for. They can't fly in GW2, you can just glide or use the griffon mount. Being able to fly in this game makes all of their unique mount abilities pointless.
