Sorry, but that quest sucks - if I wanted to play that kind of game I wouldn’t be playing WoW.
It’s part of a must do quest for a covenant story line … it shouldn’t have a quest like this in it. The physics for the hand movements don’t work with my system set up … the jumps can’t be completed reliably so the quest is undoable and I am blocked on covenant progress … so I may as well switch covenants … bleh, or quit playing that toon.
Just another way designers have chosen to fill SL with annoyances … more unpleasant work, less rewards … what a winning formula.
