Holding threat on a single target was never a 'skill' thing. Tanking one thing in general is rarely all that challenging. Holding threat on multiple enemies if it required more than just spamming an aoe move like Flash/Overpower did take some amount of skill, as evidenced by the many people being less able to do so than others while juggling all the other things a tank should be doing.

But we got the spam route buffed, so dungeons will continue to be 'mindlessly aoe all the things' unless something is actually dangerous enough to warrant killing it before everything else. Which seems doubtful, because then people would whine that not everyone has the same CC options available because everyone has to be equal at times. -.-

Mindless aoe is the most boring thing to do in MMOs.
