Here, it's pure math: there are 14 creatures in the reserve (which is too many, in my opinion, for creatures with 10 HP). With two reserves on the first week, you get a stack of about 70 guys, plus or minus a bit. If you treat your citizens carefully, on the second week, considering the growth in the Citadel and one native hero, you get a stack of around 150 creatures. We also take into account the fact that the creatures are tougher and stronger on the grass than the troglodytes, and the fact that by the second week, the hero is close to level 10. Add in the horses... Wouldn't such a horde do what Shakti does on the first week? ;) In the maximum difficulty, there will just be more losses.
