Vaal Pact & Dual Wield Swords

I've been thinking about going some sort of vaal pact build because it looks fun. Most people seem to say you should go claws for the extra life leech scattered around. I was wondering if there are any builds of using swords seeing how many swords damage and dual wield nodes there are in the area. The problem is I think it would be way to weak to play like this.

Was wondering if there were any builds or suggestions like this style that people have come up with.

After a certain point how much leech you have ceases to actually matter. You can go swords if you want, you'll just leech less.
