I finished that playthrough, had a lot of fun and am gonna push it as far as I can. Hopefully to UVHM. I just overprepared too because I had a shock Lyudmila and a Bee shield which ended up one cycling the warrior. Didn't even need slag.
I've never done it before because I didn't really get the game. This is my first playthrough where I feel like I'm properly in control, I got to TVHM but I get bored of doing the same campaign over and over. I should do all the DLCs
