Splitting is considered cheese? as it's a +3 enhancement, I've always felt it a fairly balanced option that makes ranged weapons actually viable. I didn't include it because I didn't want to muddy the math with (minor) optimization.

18? I'm seeing:
  • 2 from +6/+1 BAB
  • Up to 4 from Rapid Shooting
  • Multishot doubles that to 8, since you can only add one arrow at this point.


Still way to much though! Deadly skill already gives a huge damage boost per arrow, which also probably needs to be toned down.

I am not entirely sure how to make the Volley archer viable without being OP yet but I'll get back to you if I think of something. (Possibly scaling back the multiples or giving one point of multiplication that scales up (x2 to x3 to x4 to x5) or something like that.
It might be worth looking at the Volley rules from Heroes of Battle (page 68).
