for endgame, id rather use 2 socketed 1h crossbows to get a bonus 200% crit damage not taking into account any modifiers or skills. when your running perfect gear and have a high crit rate which all characters need, i guarantee you it out dps's a 15% flat damage boost a bow receives.
i dont know what the damages numbers on each weapon type max at, but it would have to be significantly better on a bow or 2h crossbow to beat 2 perfect one hand crossbows.
but i dont think anyone is at the point where their weps are "perfect" (as high as damage can get) and because of this, its go with whatever is best at that point in time.
From: binny3 | #006 actually 1h xbow + quiver also gets the same 15% speed bonus as 2 1h xbows.
if consider the fact that you gotta have the dps ratings of each handbow at par with each other, i think just using a quiver saves you much more money, with more or less similar stats and dps. That with the extra crit damage from using crossbows, you are pretty much set.
