Well, it is always up to you. A standard Rage hits hard and with a speed build he hits a lot. If you go hybrid you have to decide how much you are going to hybridise.
You can get Called Shot, it works well with sunder armour. Then get GW (8:2 skill ratio) . If you want to go further you can get Hamstring too, and will have to put points into Feint (6:4 skill ratio).

I realy like GW on my theatric. He can stack up heavy bleeding with exotics in a round or two.

But you will have planty of opportunity to change builds around.
