[3.3]RoA Raider/Assassin help please!

I wanted to play RoA this league since the buff and all, but I couldn't really find any recent guides for RoA anywhere, I followed an ice shot guide and altered it a tad to benefit RoA instead of Ice shot, and I converted to fire because I wanted to use Herald of Ash. My main issue is I've never really got past act 5 before, and I'm actually enjoying myself so much that I see myself getting to maps and mapping. I don't really know if my passives are any good or where to really go from where I'm at. I don't know what items to look for or what to link RoA with. Any insight would be appreciated! Currently level 49, and just started the walk back from chamber of innocence in Act 5
