As of the writing of this blog, the tank path for the Barbarian, the Sentinel, will be undergoing changes in the next patch. Therefore our coverage of the Sentinel will come at a later time.
The following selections are for the DPS path for the Barbarian, the Blademaster.
The idea behind the basic build is to build rage as quickly as possible and then to use your encounters while raging.
At Wills: Sure Strike and Brash Strike
Encounters: Punishing Charge, Frenzy and Axestorm
Dailies: Savage Advance, Crescendo
Class Features: Steadfast Determination, Steel Blitz
Feats: Mighty Blade, Rampage, Steel Reaper, Overpenetration, Offensive Recovery
