Fluff, you pretty much have to commit to dual wield or two-hander to optimize your skills. You can always respec later. At that level, I was putting points in two-hand expert.

Lacerate is also nice to have. At max rank, it was doing more than 540 damage over 12 sec without any points in Improved Lacerate. I read somewhere that using it in PVP against casters and assassins is an advantage because assassins can't sneak and something something with casters (not really sure because I don't PVP and I was half listening. I just like to see the bats bleed while I'm killing them. )

Rotor Storm is pretty useless unless you PVP with rangers (from what I heard) and I have zero points there. I maxed out Fearless to increase the time for Courage instead. Thundershout was also pretty useless to me since I have Cleave maxed and, after putting everyone to sleep, all my attacks tend to aoe and wake them up.
