Anyone have any ideas on how they're going to tackle Grandmaster Ordeals?

For the sake of experimentation, I built a set around Warmind cells. I had gotten a few good rolls on some Seventh Seraph weapons (as far as good rolls can come on them, notably the hand cannon) and I had all the mods so I figured what the hell. I went with Global Reach, Rage of the Warmind, Tyrant's Surge, and Lightning Strikes Twice. I ran Shinobu's Vow for double skips so I'd always have one -- the more cells the better, I figured. And I could proc a cell whenever I wanted to, for the most part.

But boy were they lackluster.

I ran Broodhold on Master this week once before with two sidearms (Enigma's Draw with anti-barrier and Devil's Ruin) and a Night Terror. I was LL1025, and it was a little rough, but I could just shred those Champions. It's a build that's worked well for me in previous Ordeals, but I wanted to see if the Warmind cells could compare. They barely put a dent in Champions, let alone bosses, and they are an absolute pain to shoot. I ran the Officer Revolver and VY-7 with Xenophage for heavy, and it was really tough going. The Warmind cells were great for ad clear, but otherwise pretty underperforming.

So I went back to the double sidearms and sword and just blitzed the Champions, and I found myself being able to take barriers down unassisted and then shred the champion before they fully recovered from stagger. This was tougher on the Unstoppable Ogres, as they could take a few more hits and if they slammed, it was a one hit KO on me if I couldn't get the guard up. I'd dodge and stun them again, then finish the job. But it was tough enough just 5 LL below 1030 -- I can't see this strategy of blitzing working if I'm 30 LL below the Champion, even if swords are in a very sweet spot.

So what builds are you thinking of running? I guess if there were Warmind cells everywhere because people are throwing Arc grenades like crazy or making a lot of Solar splash damage, then you could just keep popping them, but it still stands that breaking barriers would be pretty hard with the Seventh Seraph weapons, even if someone or everyone was using Eriana's Vow. And the cells would do crap damage to the Champions at that level because they're already rather weak at just 5 LL below. Or is there a Warmind mod combo I'm missing?
