Well both are great.... BS/Regen is more clicky but has the potential for a lot more survival since...(i believe) you can softcap defenses and have a lot of regen and heals on top of it. BS/WP is also great as you can softcap to all but Ranged Smashing and has regen and resistance as well. BS/WP is also toggles not clicks so there isn't any redraw which...while it doesn't matter performance wise always breaks the flow of combat for me. Honestly they are both very strong combinations.
I know this isn't on your list but one vote for BS/Shield here. It may not have as much synergy but for me my BS/Shield has been one of my smoothest scrappers leveling up and it is nice to be able to softcap melee as early as level 12. BS/Shield also makes it much easier to softcap shields if you rely on parry for at least part of your melee defense. It also looks great. This may not be as much of an issue for you but I like the sword and shield look. Plus you get shield charge and AAO which are both very nice for added damage.
Regen is really good, and I believe that Bs/Regen was a popular FOTM a while back, and I can see why. I personally don't know a whole lot about Willpower, except that as previously mentioned, regen requires more clicking, though it isn't unmanageable.

Hello everyone, I was just hoping I could get some feedback from a few broadsword users, and have you guys tell me which secondary blends well with broadsword. I pretty much have it narrowed down to Regen, and Will Power. So any opinions or feedback will be appreciated.
Thanks.

The answer is yes. Either of those secondaries will synergize well. Both will stack well with the mitigation in parry. Regen is a bit more click happy and has a wider range of performance. Willpower is strong overall but lack peak performance and a heal.
Broadsword has hard hitting slow attacks, which have long animations that prevent you from click-healing yourself while they're in progress (with regen). I'd favor BS/WP, the +def from Parry and the KU/KD from the big hitters will offer enough mitigation to let RttC do its thing
Willpower, definitely.
You will have solid end. management, and a lot of survivability. The only drawback is that you have to wait for QR until 20. Other than that WP trumps Regen IMO

I have never play a BS/Regen pass lvl 10 but I have a lvl 50 BS/WP. Both are great builds, but I like the BS/WP better. BS/WP is a beast of A scrapper and is hard to kill. BS/Regen is a great scrapper too but it is harder to learn to play and the redraw can get a bit annoying. But like I said both are great combos and fun to play.

I've been enjoying BS/Shield alot, but if you've narrowed it down to regen and WP, id favor WP
Broad Sword/Regen and Broad Sword/Willpower have very comparable survivability. I think it's a matter of how active you want to be in your own survival. If you just want to toggle on and concentrate on killing, go with Willpower. If you like more control over your own survival, with both the highs and lows that accompany that, you might enjoy Regen more, but it can be a school of hard knocks.

Willpower won't cause you to redraw your weapon durning the normal course of a fight; whereas Regen will. For this reason alone I'd prefer Willpower, but the actual survivability should be fairly consistent between the two secondaries.

Willpower. I will however throw in a vote for BS/Shields. Very theme friendly and when you get some dough you can soft cap it and go to town. Not to mention the beauty and awesomesauce that shield charge is. 
The development team and this community deserved better than this from NC Soft. Best wishes on your search.
I was going to try BS/WP at first, but then I decided to go with BS/SD and never looked back!
And yes, build-up + shield charge IS awesomesause!!! 
I've got both a lvl 50 BS/Regen and a lvl 50 BS/Shield.
Both are very Awesome.
It's worth saying that BS/Shield is Awesome. Great Synergy. Phenomenal damage Output. And one of the best Attacks in the game - Shield Charge!
Also hella expensive to IO slot, though, so if price is a factor . . .
But if i had to choose between WP & Regen, well I've
got a big soft spot for BS/Regen,
So Vote 1 - Regen
(unless you have the Inf for shields)
