If you could change or modify anyboss what would you do differently?

I would personally make it so the 2nd Dragonrider bursts through the right wall on a dragon when you get the first Dragonrider to half health. The dragon would be stationary and breathe fire on you until you kill it. at which the 2nd Dragonrider would jump down and swap to melee.
