Depends what you are trying to do. The most common thing to do is go arms then take deep strike as your skill at 30. Then load up on signets and enjoy ~100% crit chance for a while. This is by far the best strategy for leveling in PVE at lower levels. Then you can either go discipline for run speed or strength for berserker’s power.
Use a greatsword and then a one hander/horn (I prefer mace for stuns and blocking) for traveling around. I also carry a bow for the aoe for encounters to max my exp and a shield just in case.
This spec is not that much fun since you only use one weapon (two handed sword) and never use buttons 6 7 8 9 or 0.
That being said choose a play style that seems the most fun to you. The only tree I would discourage at low levels is tactics. There doesn’t seem to be a whole lot it offers at low levels
