Dunno much about thunder, but if you're struggling with debuffs, Hercules with MLB axe can often be better than Shingen (e.g. if using Herc moves you from 30% def down to 50% def down, that's actually a 40% increase in dmg, which can be as good as Shingen reducing your burst cycle from 5 to 3T, depending on what your DATA and exceed looks like.)

I'm also considering pushing to get 2 more Thunder SSR glaives so I can make use of my one and only Phantom weapon in Thunder.
Not sure what your grid looks like, but if you have to drop two MLB SSR weapon to accommodate 2 LB0 SSR just to activate a phantom weapon, it's usually not worth it, especially if your phantom weapon itself is LB0 (so you're effectively dropping 3 MLB SSR.) If you've done the math and know exactly what you're doing, sure, go ahead, but I would caution against burning eyes just to get a phantom grid running full of LB0 weapons. Also consider using MLB SR instead of LB0 SSR, they're often better - burn orbs to LB ones that are good, at least orbs are easier to farm back.
