There is actually a different bit of wonkiness in the Improved Manyshot feat, though. as printed, it doesn't actually give any extra benefit that I can tell compared to the regular Manyshot feat. it still states that it is based on BAB, which means that it still is limited to a total of 4 attacks. At first, I figured that maybe it was meant to be BAB plus EAB, but at super high levels, that might be relatively unbalancing, when one can potentially fire 10 or 20 or nigh infinity arrows in one standard action. so personally, until it gets errata'd, I think I will make it based on BAB + EAB, but with a limit, maybe 6 or 8 arrows. of course, this is assuming that I read both feats correctly. Did I miss something here?
