Most things in this game are scripted. This includes boss orientation, especially since tanks rarely have to position bosses nowadays. If you can't predict how a boss rotates and moves in a fight, then you probably haven't done it enough. It should be second nature.

Removing positionals on melee is like removing casts on BLM. If they're not willing to simplify the director and producer's favorite job in the name of accessibility, then they have no business touching melee.
