Well, I guess I can put some input into this but I am by no means a expert of either DB/ or /Regen BUT from my playing the set You will just be plain awesome in most every situation, your damage will be awesome, and the amount of +Regen you will achieve will definitly keep you alive, to a point. AV's will give you problems, so will Large mobs, if you are soloing at 53's+. Pretty much anything that can out DPS your regen will give you trouble. End will not be a issue. Period. Thats all I can really tell you. OH and despite popular belief the click powers in /regen DO NOT interupt the combo's in DB.

Well there are no guides for this combo that I know of. But I have a lvl 36 DB/Regen and I can give you some help.
For Regen you want +recharge and the more recharge the better. So I would take hasten, as soon as you can. Most of the regen power you will want to take but you can wait on some like Resilisence, try to fit that it when you can. You can also skip revive too. The other regen powers take as soon as you can or when easy to fit in your build. You don't need to take the fitness pool but I still would in my build I just some stamina at lvl 35 so you don't need to get it as soon as you can because of Stamina.
Now for Dual Blades I would when you get to 26 I would only do one combo and that is AV(Ablating Strike, Vengeful Slice, Sweeping Strike) you can run Blinding Feint>AV easy if you have Hasten in your build. I run that attack chain when Hasten is up and when Hasten is down I run BF>AV>Power Slice.
As for set bounes I would work on +recharge first then +def then +regen. One thing that will help regen out a lot is if you can get perma Dull Pain that can make a big differents. Hope this helps some.

Been looking for a few days now and can't seem to find any guides or builds dealing with this combination. I'm at 22 and having a blast with it. Anyone have any suggestions for it down the road?
