I just gone through "A Step Between Stars" with my level 60 Caitan - science toon.
And i have only one word - ugh...
First some of Voth soldiers did not enter the beam/swarmer room, and stayed behind door, which closed and could not be opened
- needed to repeat whole station ground map....
Then first space enemy was 5 Undine ships! - which at once one-shoot kill me with Focused Beam.
Alright - respawn - try once more - 6 or 10 Undine Heavy Torpedos - dead second time in moments after respawn....
After that i slowly managed to kill them with Photonic Fleet help.
I'm not sure what hapened, but i'm thinking the game adapted to my 60 level, but did not notice that my ship is T5 Dyson Sci-Destroyer - with gear provided from devs.
Oh - and that was on Normal difficulty
