I've got to agree with AcidRock on the /Necro. Some of the most fun I've had with my Warrior is because of his secondary skills. His build was something like this.
"Victory is Mine!" {E}
Enfleebling Blood
Cyclone Axe
Dismember
Healing Signet
Mark of Pain
Parasitic Bond
Bonetti's Defense
Now bear in mind, I've more or less made him a pretty heavy AoE guy, but its very easy to change based on different playstyles. Axe has alot of really nice condition effects, which can add to the Health and Energy you gain from "Victory is Mine!". Mark of Pain is my lifeblood, sometime's I'll swap in Flurry for Dismember, and just go nuts. With Flurry, my damage goes down on the guy I'm attacking, but I'm able to pump out alot of damage to the surronding guys, killing off his friends before I finish the guy I originally targetted. This could be easily adapted to other weapon styles, but I like the added damage of cyclone axe, which also triggers Mark of Pain.
Hope that helps
