Like I said on the other thread asking the same thing:

No. THM Cone AoE is far too overpowered for healing. Don't you remember how THMs were the ones used as healers pre Sacrifice AoE removal because we could heal everyone without even worrying too much about positioning?

It's far too easy to heal an entire party with the way the cone is currently set up.

Unless they reduce it's range, it shouldn't be used on the healing job.
