So I’m on what will be my last run for quite a while (I’m going out of country for several weeks) and I have a gripe with the scaling of game. “The Good, the Bad, and the Mordecai” is only available after turning in “End of the Line” and before removing the power core. If you turn in End of the Line and then take out the power core, the mission available icon will disappear. This means that the mission first becomes available immediately after killing Wilhelm, meaning that your character is at least level 15. However… “The Good, the Bad, and the Mordecai” is scaled to level 12, meaning that you have now unlocked two mini-bosses to farm, but their legendaries are nearly useless. (A level 12 Lyuda does not pack as much punch as a level 8 DPUH, to put this in perspective). This forces you into the Overlook fight with your best weapons being scrounged items. (Or, if you were lucky enough to get a corrosive variant RokSalt, that will hopefully be good enough)
An update to my run: This is precisely the position I was in. I had a level 8 DPUH, a shock Lyuda, and my corrosive RokSalt (level 15). I was level 17, one kill away from levelling up, so that worked perfectly. My RokSalt wasted them, and level up bonus didn’t hurt at all. I also ended up buying a level 15 Torgue launcher from the vendor in Overlook right before the fight and swapping that for the Lyuda. I survived and made it back to Sanctuary for the first time ever! I’ve since completed the mission for a Heartbreaker and will be rocking that through Wildlife Exploitation alongside my RokSalt. Done for the day, I wish many good things for this run. Maybe I’ll do the Danger Zone quest next, now that I have the Heartbreaker. I’m still only level 18 so I’ll need to grind XP somehow.
