Leapers with cold Cult of the Elements bloodline mod

Hey huys i was just ripped soo badly by like 6-8 leapers with cold element. Im playing melee - marauder with a lot of armour and i was like insta ripped at map lvl 67, i was lvl 73. I know about one another dude, also killed by these leapers (after opening strongbox). I think something is really wrong with those guys (im getting almost none damage from Order of the Frozen Sky). So maybe they need some balancing, please.

Again killed by Living dead mobs with puncture OMG :)))
