Request: Could Lucid Dreaming's Enmity Drop be Re-implemented?

[X89K1]

With the change to tank aggro now, in theory the need for DPS/Healers to control their enmity is gone. However, I've noticed that when a tank dies and leaves aggro on them, they now have no options aside from stopping attacking/healing for reducing their enmity to avoid death by auto-attacks or tankbusters.
If the enmity drop is re-implemented, this would allow the DPS/Healer with aggro to save themselves, since instead of receiving all auto attacks while a tank tries to get aggro back, the attacks can instead be spread over multiple party members.

Thank you all for your responses so far.
To further discussion, here is another question based on the above case scenario: Should the highest damage DPS be punished for a tank's death? In the event that the tank with aggro on the boss dies, the DPS outputting the most is going to be the one to die if the healers or co-tank(s) do not notice, since they will be generating the most aggro, whether they want to or not.
