VoR sounds cool. It's a weapon that I've never used before (since it's terrible online PvP). The CBF mod is most attractive to me. The cold damage though would mean less horking, which I think is helpful for single pass. Unfortunately I do not have a spare Ko lying around yet, so it will have to wait.A couple of thoughts. On the Lem I see two choices Delirium and Voice of Reason. You should have all the runes that you need for VoR, while you need an Ist for Delirium. VoR also gives you can't be frozen. I tried VoR on my Frenzier, and I think its better than Crescent moon. However, Oath is better, but you may never find the runes.
I also vote for Duress over treachery. For me Fade never seemed to get cast when I really needed it. Plus the added cold damage works with VoR. Of course you are going to have to do more with your lightning immunity than just the +15 you get from Duress.
I see you suggesting Delirium twice. Am I right to say that the draw of it is the CtC Terror/MB/Confuse? Is it that much of a CC upgrade over my current Decrep/Howl/Battle Cry? I don't have an Ist though, so again I will hold on to my Lem for now.
Seems like the consensus is to not make Crescent Moon. I will not make it then.
Duress is attractive to me, primarily for the CB+FHR. Plus it's another runeword that I hardly ever used in the past online. I seem to be managing Fade procs well on both merc and me though, so I will hold on for now. Gonna go a bit more greedy with the 4 PTopaz armour for as long as possible while praying for Oath runes/base to drop!
