I can't see Wurmslayer being bad. I'm pretty sure I saw some of my TMO guildies doing that combo in Kunark. Ideally, you'd want a fast main to take advantage of the damage bonus for that hand. Swiftblade of Zek is fantastic, expensive, but that's what I use and it's very very solid damage.. What I used before that, and it'll take a bit of doing on your part, is the
Fayguard Parrying Dagger from HS north's boss. It's a fantastic dps weapon. That with Swiftwind was the best DPS combo in Kunark, but it does proc a point blank AE. Use caution when wielding it, especially in an area you're relying on enchanter or root crowd control. You'd definitely need some other swap weapon if you went with that.
