Each build is better for different aspects of this game, and how each build compliments your playstyle. My build may not work for you, just for the simple fact that maybe I use daggers, and you want to use swords. Personally, I don't like the combat tree. I have a lot of fun w/ Imp Ambush and Seal Fate build.
If you have a main, I would suggest to stick w/ a certain build for a while, then throw some gold in to respec, to see what you like.
