maybe you're right, I liked the emblems. the treadmill is bad, what killed it for me was when I realized that they try to keep players playing ignoring game quality, lately they've been adding a lot of limited time things and players addicted to collecting are fearing of missing out especially after a decade of dedication. so they're trapped. plus the art that is not bad but somewhat different of what it used to be. all of that is tied to the loot reward, the reward philosophy. and I bet the devs are receiving orders and can only do so much to make the best with what they're asked to do. SL improved a lot on BFA, but still you're right the system was better in tbc/wotlk.
what a sad situation retail wow turned into.
