Ok so I have been doing The Balance of Power on my level 120 Paladin and I have never completed the achievement before on this particular class, I have however completed the achievement before on a previous character I had mained before in Legion at that time. Anyway As I am going through the whole process I figure out by the time I get through finally completing The Emerald Nightmare for the essences which you have to do in two separate weeks. I am like ok well I had to wait a week already just to complete the achievement, then I go and start doing the quest after that now it tells me that I need to complete the Moon Guard Stronghold in Surumar before I can proceed with the questline. So I complete that long list of quest and complete the Moon Guard prerequisite. Then I move on and it tells me I had to buy a scroll from First Arcanist Thalyssra ok no biggie I can just buy the scroll and…What I have to be REVERED WITH THE NIGHTFALLEN! Ok at this point I abandon this journey of non ending grinding and I say to myself well I guess my perseverance through this on one character I completed and got the achievement on was not good enough for me to unlock on all other characters. Why do I have to endlessly grind on each class that I have never completed the achievement on just to unlock the artifact appearance is once on character not good enough to satisfy the role. I don’t mind having to do something on each class, but this amount of grind is ridiculous I think now that we are in BFA there should be some sort of smaller quest chain you’d have to do if you already have the achievement completed, I don’t know who else likes to grind for a butt load of time but if you don’t please like my comment pass it along and get blizzard to shorten this grind for those of us who have done it once already. Thank you for listening
I would be ok with balance of power being account wide, its an achievement after all.
