Yeah, I actually didn't think much of it at first, but for level 3 shield it just keeps beign very useful. I'm over lvl30 and at Trash Coast now.
Found some legendaries since, Abaddon and a non-Lilith class mod.
I still prefer using Depressor, very satisfying weapon to use despite its 3 round mag. Abaddon to me feels more like a bullet dispersion device, a bit too low accuracy for my tastes.
edit: Finished 1st playthrough. But before that I found another. Third pearl on this severe playthrough already!
Fun gun, a great tool for close combat. Was great for taking out melee guardians. Anyway somehow I'm finding more pearls than legendaries.
