My Psyker just ran an Intel mission that had "Enemies reflect 3% of heat damage"

Dropping a Firestorm on a Skull group of enemies in a Hunt mission instantly killed me from full hitpoints.  With 3800 HP that means I had to have done at LEAST 126,667 damage from that single strike.  I've had this hazard before and it has NEVER hit me this hard.  

I absolutely HATE reflect damage as a mechanic since it just punishes you for having high damage output.  I'd love for it to be removed from the Hazard pool.

But since that's probably not going to happen, I think it at least needs to be looked into since it seems to be reflecting far more damage than it's supposed to.

Even testing with Molten Beam, ticks of 800-1200 damage resulted in me taking 60-100 points of damage.  That's more than double what I should have been taking.  Plus it seems to 100% ignore damage reduction and resist and I don't know if that's intended or not.
