The survivors’ hp and damage output scales with elite level, but apparently hit rating doesn’t.
I don’t know if it has always been so, and if it is meant to be so, and I doubt it makes much difference to anything with the S&P’s being as easy as they now are, but still I find it a bit weird.
Same thing with Survivors, Reinforcements and Turrets, glancing already 10% in E1, and around 50% in E17.
