That's normal, sewers are much harder than previous campaigns. Shadow caves are super hard elite dungeons, and they are mainly meant for higher level players who farm there for valuable drops. It's not very great place to level.
If your dying too much, buy wand set. Level 53 mastermind set (purple items) is good enough, and costs something like 20-30k. Or you can just farm it, they have super high drop rates.
