Because every other area ive gone to the mastery points are 100ft up in the air so cant be done with out the previous mounts or on quicksand etc. Gating the story behind mastery points is a terrible design. GW2 is supposed to be a casual friendly game,i dont have the patience after working all day to try doing the chef , the games supposed to be fun not frustrating to the point i no longer want to play it.
