Every single game I play (including WOW) pretty much has challenges or gear that I’m unwilling to expend the effort to do or acquire.
Loot system has been imbalanced from the start. Fixing that disparity would be great.
Delves are more rewarding than m+ which are more rewarding than raids.
And to fix an imbalance? you nerf loot that drops or give another mode more.
Or should imbalanced systems remain in perpetuity because people who use those systems want to be unfairly rewarded?
