Ligthing Arrow Build - Bow for lvl 50?

Hi guys, I have been following Martin Creek's build but now I'm stuck at Merciless (just hit it at lvl 50) and got no dmg, or atleast I feel like doing no dmg.
I'm using this bow but I think that I need something new, what specs should I look for ?



This are my two bows i have atm :$ -- ON league

Those are both fairly good bows.

At a guess, if you're on onslaught, you specced heavily into defense, leaving few points for offense. That's one factor.

The other, of course, would be your skill links. LA LMP Chain LoH, right? If you can get a 5L for WED, you will deal easily half again as much damage as you do now.
