Asking for some tips on skill building.

I've been blindly following builds from Bestiary til now without fully understanding how this game works. I've been playing on and off so I never went past tier 15 maps... so I tried making a build so that I understand first hand how to min max with my current knowledge.

It doesn't have to be absolutely end-game material. I just want to see if this can be a basis for a elemental bow character trying to graduate from yellow maps. It'll probably be revolving around LA/Barrage or maybe even the new Galvanic arrow, using the typical items and auras like Windripper and HoI...
