If you're comparing the lv 60 with the lv 50 one, i actually got wiped 3 times on lv 60.. However it only took a single attempt for me to clear the lv 50 one, thats even when i didnt know how to play properly since i only played for like less than a month compared to "have been playing for a year" in lv 60.. I didnt know either that the prey status can be passed to the npc, making the dragon attack the npc instead until those 3 wipes..
