9472 Centaur outriders deal 605 damage to Patriarchs. This is while they are standing in the storm of 32 Stormcallers (90% damage reduction)
9401 Centaur outriders deal 4758 damage to Patriarchs. This is while standing in the same position as previous attack but it is almost 8 times as much damage as the previous strike.
Even accounting for the damage range of centaurs (4-7) it doesn't make sense.
