i think the venomthropes for 1 comp is fine. as you start to reduce the amount of ignores cover armies like tau and eldar can field you inflate the value of giving huge swaths of your army shrouding. a well placed aegis and/or piece of ruin could potentially get you within charge distance of your opponent maintaining 2-3+ cover the whole time.
i don't know if it's strong enough to be worth 1 comp, but i can see the justification. i'm just saying that as a nids player i don't think it's ridiculous.
