Crossbow implicit mods seems lacking

Besides the buff to grenade skills dropping one more grenade, I basically don't see anything else besides in the start where I got one with one extra bolt, can we have more implicits for crossbows please? I want to shot my crossbow, not just drop grenades '-'

I'm trying to make a different build that doesn't focus on grenades, but never see any crossbow with a decent implicit bonus besides that one, starting to regret not creating a ranger...

It'd be cool to find some dual string bows to buff the number of projectiles with my secondary weapon bow as well, since act 2-3 onwards it seems to me like most bows are for chance to chain, like what I'm feeling with the grenades crossbows xD
