I feel they are a sad too high. Taking 250-300ish damage (without AoM) per DD. Using both thats a nice 500-600 dump. A possible solution to this high damage would be to give CL Resist buffs ;/
That is a lot of damage although they themselves do not think they are doing that much damage because the damage they are seeing on their screen is 20% less damage than what you are seeing on your screen so in their defense they will say no no not true! See my post
