Newbie Marauder, Thoughts so far?

Hey guys, I have a level 20 Marauder, this is my first character in this game.

I have tried to make it so I am able to farm efficiently, I am trying to achieve something akin to a Shadow Knight from the game EQ2 or a Reaver from Rift.

So far my build is as follows

Any thoughts please?

Honestly I'm not sure what those characters are from those other games. If you want some help though, try to give us details on what you are tying to do. 1h quick lifesteal is what I think of your build so far, but that's simply because the points you went with life leech/gain. Honestly other than those two points everything is completely standard so far. May I suggest dropping down and getting Heart of the gladiator. It will make the biggest impact at the lower levels with its base life gain.
