The things with bows however is that they can't block and this his roar is not only a HGE one but also has a pretty long reach. Being unable to block however isn't much of a valid reason not to use bows since you can attack him at any time, even when he's spamming ceiling attacks or that electric shield.

If you're going to bow him I suggest using Rapid Shots or Scatter Shots. Pierce has its uses but Khezu's aren't really that big so the potential damage of pierce shots is not as high as it could be.
