Sure thing, killed 100+ while standing like that from a house on same spot.
Problem was just when they are so many.. they're also buggy as fk and can jump up and at hit you... while you're in 2nd floor of a house or fall/jump inside the house when everything is closed.
They would need to fix the amount on less populated servers too, doesn't make sense that 10-50 ppl have to deal with the same amount as 200 ppl. o_O
