This doesn't seem to kill any of the red distinguished creatures you have and just makes Child of Melkor ping you and your opponent for an extra point. Is this intentional?

The "pings itself" is something of a leftover since the original design wayy back chanted instead - hence it limited the amount of burning by the size of the creature. Here though, it doesn't really add anything to the card.

I'll probably remove it at some point.

"All my creatures are tim" is scary. It could do with a time delay before going live, maybe?

"Time delay"? Of what kind?

I assume he means a delay from when you play it to from when your creatures actually get the ability. However, the restriction is fairly limiting in this case and Lightning Volley exists (though it only lasts for a turn), so I think as a design it isn't too bad. I am not sure the design is quite what red wants in this set, though.

This seems fine.
