I've been mastering my Jem Dread cruiser and it seems that the enemy is always rolling crits and taking half my health in one salvo.
"No place shall be denied to them, no enemy shall bar their way. They shall be proud of heart and stoic of spirit. They shall be measured and wise, yet their hatred shall burn with such heat that their enemies wither and die before them. They shall be masters of every weapon, every ploy, and every strategy, fierce in the attack and solid in the defence. They shall go where others fear to tread, and return victorious, that we all might live but one more day."
— Extract from the Apocrypha of Eons, Verse I, Chapter III
