I need suggestions for a good Predator build.

I’ve been using an attack based build on my Predator until I found out his attacks are hp based. So obviously it’s more hp = more damage, but I’ve also heard that you want to go for crit rate, and I can’t seem to find a good gear set that would create a good balance of both. Is there anything I should focus on in particular? I don’t have the resources to reroll gear consistently and I can ascend my gear to the low levels.
