Are you asking for an endgame blue line setup? You'll be unlikely to find one as no-one is really using blue line atm for endgame unfortunately.
If you're asking just for soloing, then there's no real "right" or "wrong" way to spend your trait points, just whatever works best for you. I would say though that Critical Eye, Deadly Precision and Quick Draw are useful from red, and Strong Draw, Quick Shot Focus, Volley, Blood Arrow & Exsanguinate, Split Shot, etc., are good picks from Blue. I'd also avoid Bow of the Righteous and Moving Target as tbh they're fairly useless.
This is what I'm using, but I haven't put a huge amount of thought into it as I'm not playing blue atm.
You may well want to go for Press Onward or Strength of the Earth if you want a few more heals, Pathfinder can be handy for utility if you aren't as fussed about DPS traits, etc. I would really just play around a bit and see what you find yourself gravitating towards
