Since the last revised thread was shut down due to necro, personally I wish our Companions had an AOE taunt! They can only target ONE enemy in a mob, so the rest tend to come after the player; it would be especially useful in boss and WB fights that spawn adds. This also applies to solo player as well... being able to AOE taunt adds to keep them off our Companion healer or Companion DPS. They could offer a single target or AOE morph... and with Armories you could switch depending on the content you were playing.
For regular play, I know Templars can use Radiant Aura which works as an AOE taunt... and tends to bring every enemy in a dungeon to the party! Or at least I think it still does, it's been a few years since I even slotted that skill, but I know I was in a dungeon and used it and suddenly was drawing aggro from enemies far and wide.
