I started the Campaign with the new Psyker class. The difficulty balancing seemed OK even if there where some instant death rooms. For example a gas trap with 4 teleporters, swarming demons and an unwelcome warp anomaly. All in all I kept my char mostly alive. But now I'm facing a ridiculous challenge rating of 560 for the next Chapter Mission. I don't know if this a bug or intended. But if it is seriously intended that means a lot of boring demotivating grinding, as my psyker's rate is just about 170.
Has someone else a similar spike in the challenge rating?
