now, during the first rounds, the doom track advances slowly (or not), but the terror level moves on. if the investigators don't close gates, the doom track will soon advance every round, no matter if there is a monster surge or not. this makes closing gates without sealing more interesting.
thematic explanation: the ancient one needs open gates and power to prepare his return. when many gates are open, or when he chooses to not open a gate (because there is already one on that location), he can proceed his preparations to return. when there are only few gates, he has less power and focusses this power on opening the gate. the citizens of Arkham are unsetttled by sudden gate openings. when there are already many gates open, one more doesn't disturb them that much.
note: it makes only sense to use both at the same time, as it's more a variant given in the form of herald/guardian, than a real herald and guardian.
