WHITE MOBS

can ya toon the white mobs down? people shouldnt be able to fight 2 and 3 big rares or maybe even a boss and a couple of rares at the same time just to have 1 white mob 1 shot ya through es and health. is this how its intended or is it a glitch or bug that allows a single white mob to literaly rip someone to pieces?
im only lvl 83 and been farming t9 maps in hope ill see a 10, every once in a while 1 white mob is stronger than a boss? and does 2 to 3 or even more times the damage a boss does. im also in hopes to actually see a t 10 map soon seeing as i been on 9 for a good while now, but 83 and getting 1 shot by a white mob in a lvl 9 map? i have plenty of health and es to survive groups of mobs but that 1 white mob ever so often kaboom!!! dead
