Just hit 100 on my lock, leveling as destruction. Do the Legion opening quests and get to the part where I pick my new weapon and got through the stages. Get to the part where Guldan says to take the scepter and can’t click it.
After researching, I find that this has been an issue since Legion launched and it was never fixed? Shameful.
After trying several different suggestions I was finally able to complete it after about 20 mins.
Pretty disgusted that you haven’t fixed this after 4 years. Especially a glitch that prevents you from progressing further in the game.
