From what I understand, the vista system was built because GW2 didn't have the same transport system as WoW (Flight Paths) to be able to show off the world. So, instead they made vistas to give the players an incentive to view the world (I may be wrong on the origin story). Anyway, Which vista's are your favorite? I've always found the "Plaza of Lyssa" vista in Divinitys Reach to be absolutely incredible.
