I agree with many of your points. I still go back to TPS quite regularly.
My issue with TPS isn’t so much the mechanics and loot, it’s the level design. I’m trying to get through UVHM with Athena. My next mission though is through Pity’s Fall. Ugh, that also means Veins of Helios isn’t far off. I’ll eventually do them, and probably enjoy(ish) them. And there’s trying to find your way around the space station.
I do love Oz kits and slamming. Slamming in BL3?? Really? The mantling is O.K. Sliding, meh.
I used the grinder maybe three times. Meh.
Did you play Claptastic Voyage? I would love to see the return of glitched weapons.
