With the potential for say 3-4 bow strikes under observation or high rapid shot/precision or high level or all three. My real problem with hunters is that you can't maledict enough to not care about low damage per strike (like say a dagger spec) and you don't do enough damage to overpower someone. Couple that with low to zero lagging ability and you end up with an ineffective class at best.

You could also up the damage per strike on bows, but I think more attacks makes more sense then bows having a 40 avg.
