helm dominator, necro 3. drow 1 hit kills it and gets 200g each. wheres the balance in this?

you play chen or beastmaster, drow 1 hit kills your units. its very frustrating.does chen always have to run away if he sees drow? its ridiculous.

the way it works should be similar to against visage or warlock minions. only dealing bonus damage instead of instant kills!!
