Positionals were always a poorly used mechanic that added little to nothing to the game. You were either with a tank or they might as well not exist, there is no class in the game that has crowd control and needs to set up and like Rogues did in WoW before. The only major thing it ever did was cripple you for playing a monk solo because... reasons? The fact they have already watered it down down as much as they have or are just turning them off in some content. It isn't doing anything but making its continued existence more meaningless and showing how inconsequential they are. The bosses spinning around because they absolutely have to face their target for any abilities is just adding to the issues.

They can take all the cost savings in server performance to add more things to the cash shop.
