How should I finish my King's Barrage build? Hybridize or all-in on crossbow attacks?

I'm currently at 28 pact points earned, and my King's Barrage build based on crossbow damage and water spell sustain has been pretty locked in for a few points now. I'm curious what people are doing with their points once the core pacts are locked in. I know there's a pact to get max accuracy roll chance +5% per tile between you and the target, is that reliable for brute forcing high ranged defense PvM? Or are people more willing to tech into hybrid melee at the end? I'm not considering thorns since the cb is 2 handed, so it would likely be a 7 point dip into making whip more effective. I haven't seen much discussion on the finalizing of the Barrage build so hoping to get some insight into what crossbow mains are doing. Regions are Wildy/Asgarnia/Kourend, I know Olm hand in CoX is a bigger barrier but I have a friend group to run raids with and they're fine with me not being as big of a contributor at that stage, they can dump melee damage way faster than I could anyway.
