At that level I was doing the most damage with 2HS - the Sword of the Crypt Crawler, which healed, and the War Marshalls Staff. I absolutely loved the Sword of the Crypt Crawler through level 54; it was one of the funnest weapons I ever used, as the effect was terrific looking and very beneficial. I was much more effective with 2HS fear kiting the Griffons in JP and the various mobs in Eastern Wastes. I think at level 49 I had the Ardent Protector, or such, and continued to get better 2HS through the earlier 50's. At level 55 and above, I started doing much more damage with the 1HS duel wield weapons avaliable, and am not using 2HS much (even the Windblade and others I have).
