Just as the Title says, The dragon spawns and takes up an hour of your time for no reward but the 80pts for the day(Which its faster to just do the normal dragons). Even on Asura we still yet to kill this thing. People have started skipping it entirely and just waiting a full hour at the next Domain Dragon.

If there was better rewards, aka maybe a random item or Wyrm Ash, or at least weaker than it is now id imagine ppl might even bother fighting it. But as it is, its just making people wait a full hour for next Spawn.
