What am I doing wrong

[Longhunter]

There was a time when I used to put a point into Jab and use a spear/trident until I found a good bow. That would sometimes not be until late Act II. Meanwhile I would place all other points into the Bow/Crossbow tree (plus Critical Strike). It was not until I got Ice Arrow that I would switch solely to using the bow.
I stopped doing this thinking it wasn't the "correct" way to build a pure Bowazon.
Now however, I am thinking that that one point in Jab and a nice socketed spear could get me through some of the tough spots.
