Mobs damage after knockdown

Ok seriously, did they add a frenzy mode to mobs when they knock you down after sprint? I just got knocked down by a pack of 4 white mobs in act 3. I had 1200 ehp. If i was on my feet I could let those 4 white mobs (rats in jiauanis machinarium) hit me for 3 seconds and they would not even have gotten through my darkness layer of defenses, let alone 1200 hp worth of damage. But I get hit to the ground, and even with potting they explode my defenses like they are not even there. Stop making the TRASH MOBS be more difficult than a god damn act boss PLEASE. STOP putting in things that make playing the game feel like a chore. FIRE WHOEVER IS SO IN LOVE WITH KISS/CURSE IT HAS TO BE ON EVERY GOD DAMN THING IN THE GAME!!!!!! Kiss/curse is supposed to be for MASSIVE MASSIVE buff items (Like CI, perfect use of the Kiss/curse mechanic), NOT "gain 25% more ele damage of type 1, lose 50% of the other 2" and you cannot even improve it. NOT oh if you want to go fast better not get hit AT ALL or you will die.

I even went in and did a test on the damage. You lose your armor and evasion if you get knocked down. There is no other answer for how a group of mobs explodes 500 hp of darkness and energy shield if you are on the ground, but do not even dent your darkness on your feet. GGG Please fix this dogshit mechanic. It has no place in the game period.
