Nope, I had precisely the same result as Vinterbris’s Axton. One completely failed attempt at the map at 46, then a second attempt after hitting 47 that was difficult but successful. If Krieg were the same level as the enemies in Sawtooth Cauldron (as he is in NVHM and UVHM), yes, it’s a very fun map. Anyone going in at the natural level (46-47) in TVHM is going to have a very bad time due to the enemies being at 49.
On topic - I took Sal through the Dam Fine Rescue. Surprisingly, it was a painful, death-filled, almost Axton-in-UVHM-like run of suck. He hit 39 around the whirlpool (and did get the challenge, yay 0 fuse time slag singularities!) and side-graded his dps gun from the Casual SWORDSPLOSION!!! (33) to a purple Practicable Development (39). Eventually got to W4RD3N, and that fight went very smoothly just because it’s a set-piece where he could blast a rapid-fire quad into the crit spot and kill it before the adds could do much.
At first I thought the problem was Sal’s shield (level 35 Impaler, so 3-4 levels out of date for this run). But it’s no weaker than the random green shields dropping during the run. So I’m starting to think shotguns are not the all-purpose weapon for him that they have been so far - surviving out in the open getting close to enemies just isn’t working anymore. Using a Hyperion pistol (if I had any at this level, which I don’t…) from cover, and only switching to a shotgun when many of the enemies are dead seems like it might work better.
