One for All Kindred

I don't know if this is intentional or not, but if multiple are attacking the mark(they all get the same jungle mark) Only the one who lands the killing blow gets the mark. Would there be any way for them all to get the mark, or if that's deemed too OP(it would only be OP with amazing teamwork) can they all have separate jungle camp marks. because is at a severe disadvantage in One for All.
